  1. All stock 2006 Mega Cab. Truck was terrible to drive – slow, terrible shift points and ran hot even at slower speeds while going up any hill w/o any of the power it should have.

    Bought and installed MM3 tuner over a month ago and it woke the truck up. The lockup in 3rd on a consistent basis keeps the truck ready for immediate throttle when needed. Going up long 7% grades, unloaded, the truck stays cool and maintains a constant speed.

    Going down the same grade all I need to do is slow down to the decent speed and the truck stays locked up in 3rd and hold s the truck back requiring much less breaking. Tow/haul will do the same thing but now I don’t need to enable tow/haul and just focus on driving.

    The Sport Tune is ridiculous. The truck is stupid fast but I will warn you – do not use this tune unless you have a built transmission. You will be tempted to use that tune for everyday driving – don’t 🙂

    If anyone is on the fence about buying custom tuning for their truck, don’t wait all these years like I did. You will not regret it. Rob was quick to reply with any and all questions I had.

  2. I recommend to anyone looking for a first class tuner for a Dodge common rail 5.9. His tunes are very responsive and the truck is a joy to drive with the new shift schedule. I also had a bunch of bugs in my truck and Rob helped me a lot. He got me the ecm recovery flash so we had a reliable starting point (I bought the truck with efi live in it). My truck had some upgrades on the transmission and bigger injectors(30%) and he is not a smoky tuner. Even with the 210hp its easy to control smoke with your right foot. If you are searching for a place to buy your MM3/tunes look no further

  3. Rob was very helpful with advice, and getting me set up promptly with my new tuner. His tunes work great, transmission shifts the way it should have from the factory. HUGE improvement over my edge evolution I previously had. It’s a new truck. I highly recommend! 11/10 would buy it again!

  4. Just installed 4 tunes from Rob and they all run and shift WAY better!
    When I heard Rob explain what he had done in the tunes, I was sold half way thru his video demonstration. Even more happy after driving my 2004 5.9 with 184,000 miles which I bought new. With his tunes, truck runs and shifts remarkably better than it ever has since I received it.
    I had looked into a couple other brands prior to finding mm3tuning.com and my perception was that they hadn’t focused on tunes for my particular truck and transmission.
    Extremely happy with my purchase!

  5. Rob,

    I just want to thank you for the vastly improved mileage and drivability of my truck. I don’t know what tune it had before, but your economy tune gave me 3.5 mpg improvement over a 1500 mile trip, and it drives so much nicer!! The trans shifts SO much better! That trip was without towing, on the economy tune. I’m doing a trip to Texas later this week on the towing tune, pulling my 35 foot fifth wheel trailer. Will let you know how that goes. Feel free to post this as a testimonial.

  6. So I was thinking between efi live and this but let me tell you I am so glad I chose Rob. He by far exceeded my expectations and was super patient with my lack of computer knowledge. I STRONGLY recommend you buy from him if you decide to go this route. All I can say is turbo and psi 🥰

  7. Excellent service and an excellent product!!. I would not hesitate to purchase again. This has really helped, especially towing and keeping the heat down. Second gear lockup is a life saver.

    Thanks Rob again,


  8. I have to say Robs tunning for 06 with the 48re is fantastic. My truck had EFI live on it but still shifted Unsatisfactory So after some research I found him and am very pleased how it shifts now and the costumer service is fantastic. I will recommend him to anyone that is looking for there truck to be tuned. Thanks Rob for putting in the work

  9. Have to say by far the best tuner setup and best customer service in the industry of tuning. I have a 2006 2500 and I stumbled across mm3 tuning through my research and was sold with only a short convo with rob. Hands down the guy to go too for tuning and any other questions .

  10. I have a 2006 Dodge 2500 and mostly tow a 10,000 lb travel trailer with it. I was looking to get a little more “oomph” out of it and boy did I. Rob put together a 60hp and 90 hp 12V tune that are incredible. It’s like driving a completely different truck.

    One of the biggest reasons I went with Rob was the ability to tune the transmission as well. Two days after installing I left for a two week trip on the Oregon coast. Truck performed great and I even asked Rob about some fine tuning for the transmission after I got home, to which he said he had a solution and would put something together. Try getting that kind of service with an off the shelf product.

  11. After doing the research Rob was the only tuner out there I found that actually took the time to change and enhance the tuning on the 48RE trans. I picked up the 3 tune packed 30-60-90. So far I have to say it has really changed the truck drivability. The shifting is solid. The tunes are perfect. I tried a different platform that just did not even come close to these. Every time I have asked a question Rob got right back to me. I would suggest Robs programing for any of the cummins.

  12. Hands down rob is the best tuner for the cummins platform and the system is by far better then any off the shelf tuner for these trucks my truck was a one off combo of newer engine in an 03 truck that i was told could not be done by a bunch of different tuners and shops and talked to rob and he didnt hesitate to say we can figure it out and make it work and that is exactly what he did got the base tune about spot on first try and has been great when it comes to customer service one of the best ive ever delt with. He knows what he is doing 100 percent for sure hands down the only guy i will ever use for any custom cummins tuning put his mild street tune in truck and its amazing the difference compared to a standard street tune of approx same hp from an edge tuner that i have used on previous trucks theres a night and day difference bottom line is you want to put a tuner on your cummins robs the guy for sure. Thanks agian rob

  13. Put 3 tunes in my 06 2500. Rv transporter And I do a lot of miles. My first 10k miles (3 weeks) are all smiles with these tunes!! I see all terrains from flat land to Rocky Mountains and I put everything threw its paces and the tunes do it very well! The transmission works great for towing And shifts nicely.

  14. Just installed the mm3 today. Loaded the 12v 90hp tune and wow a world of difference. The 48re tune is better than putting it in tow/haul when stock. Rob is the man quick to respond to my questions and getting me the tunes. Anyone looking for a tuner this is by far the best I’ve used

  15. I don’t know what to except, wow! I’m by no means a lead foot, after installing the tow tune, immediately the shift patterns and solidness were felt. I love the TC lock up, the tow/haul mode change and the power even on the tow tune is punchy. The power and torque in 3rd was awesome. Great job Rob, stand up guy, professional, patient with my issues and willingness to go the extra mile to help a customer, bravo Rob!

    Look no where else…

  16. Rob was super helpful, I know roughly what I wanted and he pointed me in the right direction, I chose the 2 tune option and had a slight hiccup with one, he knew exactly what to do and instantly emailed me a new file and was mind blow about the difference it made. I had bought the smarty touch thinking I could dabble in tuning myself but I just couldn’t get it to work, leave it to the professional to do the hard work that knows what he’s doing.

  17. Rob was great to work with. Answered all my questions in a timely manner. So far the tunes are awesome. They really show what the truck and tranny are capable of. I bought four from him with sotf and the mm3. Great combo. The 12vhp tune is awesome. Will be buying more from him down the road

  18. Best bang for your hard earned buck. Rob was awesome to work with and answered all my questions. Rob emailed me my tunes the same day I emailed him my stock file. It’s a night and day difference in the trans tuning. Definitely worth every penny. I bought his 4 tune package with monitor and will be asking for custom tuning for my truck when I do some fueling and turbo upgrades along with having my transmission built to handle all the awesomeness.

  19. Thanks to Rob and his excellent tuning skills!

    I received my tuner and files quicker than I ever imagined. Working with Rob was exciting and easy. I had some difficulties with the download process and he quickly adapted to meet my technology capabilities. That is truly great; don’t see that kind of flexibility anymore.

    After downloading and installing Rob’s tunes (and I’ve had three different programmers), I instantly noticed the power. The biggest change was how the transmission shifted. The change got rid of the 2-3-2 shuttle shift. It upgraded shift points and torque converter lockup, which makes my 2004.5 Dodge 2500 48RE Cummins drive the way it should! I LOVE the 12v tune.

    Rob has done his homework. I wouldn’t go or use any other programmer/files.
    Thanks again for your quick responses and efforts!

  20. Robs tuning was a huge improvement over my can tunes that I had before I got the mm3. Rob really took the time to get my tunes dialed in and running great. Customer service was unbeatable I never had any excessive waiting periods for my tunes or questions I had. Also the trans tuning is impeccable, the noticeable difference in shifts and shift pattern is really nice. The interface with the mm3 tuner is really user friendly and easy to understand also Robs instructions are really helpful. I would highly recommend Robs tuning to anyone looking for a major step up in their tuning needs whether it’s hot rodding or just towing.

  21. Robs tuning is awesome. It took me quite awhile to decide on who to use and after going back and forth between a few people, Rob is who I chose. He responded quickly and answered all my questions, whereas others either ignored me or didn’t have a good answer.

    The tuning is fantastic! What an update for our 3rd gen trucks! The trans tuning completely changes the drive-ability of the truck and the power increase is great. No comparison between the MM3 and a box Tuner. I went from the Smarty S06 to this and am very glad I did. EGT control is there, better shift schedule, better power and response, and on the fly tuning! Check out my reviews on youtube if you’d like @ Brandon Turos.

  22. Love this product and respect this tuner ! I’d done my research for so long going back and forth with the big companies and scrolling around I see this page. Moments later I contact rob and within a short while of a man having a job and his own on the side I have a great conversation about his tuning and what I should and shouldn’t be doing with my truck a book of knowledge and know how . After making my decision to finally pull the trigger I received my package very quickly and had to hurry and install eveything was made simple thanks to rob step by step he will help you in a kind manner no matter the situation he will help you. After some issues that were then resolved with hookups and such my 2006 2500 cummins was running like a top better than new with a custom 12v tune makeing it truly iconic and the power and fuel economy is incredible. I must say the most impressive is robs in depth tranny tuning this is where is shines it shift like nothing else. I personally can’t think of anyone better to go with for tuning and truck advice a customer forever you have gained.

  23. It feels like a whole new truck. Towing, it shifts when it should, and very smooth. There’s no shuttle shift with light throttle when you’re stuck in traffic and no clunking into gear.
    I got the 4 tune package; MPG, Tow, Street, and the 90hp 12 valve tunes. The 12 valve tune is a blast to drive, really reminds you of the old trucks.
    I’m not sure how Rob cracked the 48re codes, but the shift points, TC lockup, and overall greatness that these trannys have to offer has been unlocked, finally.
    Customer service was excellent too. Thanks again Rob

  24. Rob definitely knows how to make these trucks run right. My personal favorite is the 90hp street tune, it really woke the truck up. If you have a 3rd gen with the 48re this is the site to be on. Thanks Rob.

  25. Love the Tow tune I got. Works great with my truck 2004 HO 5.9 twin disc southbend clutch 6 speed NV5600 4X4 3500 DRW. I have BBI stage 1 injectors and a 63/65 turbo. I tow a 36 foot fifthwheel toy hauler (dutchman voltage 3200). I’m able to hold 80% engine load at 1250F EGT. All the other tunes I got elsewhere were not even close. I’m very happy with this tune. Great drive ability with and without trailer.

  26. 2005 Ram 3500 Laramie I have always enjoyed my truck NOW I Love…. driving my truck. The difference in performance is remarkable I got the MM3 the tow tune and street tune but the remarkable thing is the trans shift points !! Truly the transmission feels so much better “If the truck could talk I know it feels the same” Drives more like a new rig she is so much lighter on her feet LOL …. believe me when I say I now want the 210 HP but I don’t think that’s a good idea knowing me.
    Rob is awesome to work with and does all he says he will do and more. I believe this upgrade is going to extend the service life of my rig and may very well be the best investment I have made in my truck. If you have a 3rd Gen 5.9 Ram do your truck a solid and talk with Rob on what is best for you.

  27. I am blown away how much better my truck is after installing Robs tunes. The shifting is so much better I don’t know how he did it and dodge got it so wrong with the shift points and lock up on the 48re. I pull a 12000lbs toy hauler all around Southern California and was looking at a newer truck until I found rob and I’m glad I tried him out before spending all that money for a newer truck. I have a whole new love for my truck now. Thanks rob.

  28. I bought the tuner and 4 custom tunes from rob when I say this guy knows what he is doing he honestly does I no longer have the shuttle shifting the transmission shifts like it should I have full control when towing and the best part is the egts drop a lot compared to my edge dealing with him is the way to go hands down thanks again rob (2005 Dodge Ram 2500)

  29. Just got tunes from Rob for my 5.9. They really woke my truck up! I couldn’t be happier with how my truck performs now. Thanks Rob!

  30. Wow I don’t know where to begin my problem child 06 is back to normal! Being a Dodge fan for a long time, I scored an 06 2500 4 years ago that I’ve kept up and currently running strong at 185k. After burning up a transmission from a blizzard I had a Reman trans installed and the truck was never the same after that. They always say the reman is as good as the builder. There is truth to that however the software running the truck applies to the same rules! Dodge fumbled on this during this time. Having a reman installed I suffered severe shuttle shifting, lower pressure, higher Tran temps and taking the kiddo to school in the morning was a nightmare!!! Rob the man, has dug down to the very beginning surface of what these trucks were built on and created his own leaving the results on the table as an absolute win! Your not getting just an engine tune to run it hard, your getting the fundamentals of what is needed to run normal and harder! Creates Longevity when your not a lead foot. If you have doubts on a 1k addition, it’s like a better health for you but for your truck!

  31. I talked with Rob for about 2 months before ordering his MPG and Tow Tunes. I hadn’t updated my Smarty Touch, which needed to be done before I could load custom tunes. Rob walked me through the entire process, including the glitches during the update. Wow, was I ever impressed! With the MPG tune, the power feels about like the Touch level 3, but with the changes in how the transmission shifts, it feels like a totally different truck. For me, the greatest thing is how it downshifts now, just like it should have from the factory. Thanks Rob!

  32. Just uploaded my tune and it worked great. The transmission is night and day better, should have been like this from the factory. Rob was very good to work with, answered all my questions and tune came back very quick. This is a must have.
    Thank You

  33. Thank you Rob, Watched your video on the 48RE tow haul mode and decided to get the MM3 tuner and full tune package. your tunes did everything you said it would do. I pulled my travel trailer over the coast range this weekend here in Oregon and I couldn’t be happier with the shift pattern you set up. Third gear lockup is awesome on the hills when pulling and my tranny ran cooler too, also when just cruising through town at 40 mph it stays in third where it really should be instead of lugging in fourth gear.I’m one happy camper Rob! Good job with your tunes.

  34. I was fortunate enough to stumble across Robs channel on Youtube and decided to reach out. He got back to me immediately, I purchased original tunes from him and loved them. Then I saw that he had new ones and updates, I reached out again. Couldn’t be happier with the outcome. It made me find the enjoyment in driving my truck again. If you want solid product and delivery on what is promised Rob is the man. Thank you again for the work you put into this.

  35. I don’t know where to begin. After putting a tune in from Rob my engine and tranny immediately woke up. The tune brings out the perfect amount of power from my cummins coupled with perfect shifting makes driving my truck even more fun! If you want safe power to your truck Rob is the guy to get it from. He truly knows these trucks inside and out.

    1. Rob is awesome, answered all of my questions very promptly. Pulled my 13,000lb RV this past week and couldn’t be happier with the tunes. The truck didn’t downshift on small inclines as it did before and the added torque was very noticeable. I highly recommend Rob’s tunes, really woke my truck up.
