Thank you Rob for the mpg and tow tunes for the mm3. It’s like a brand new truck! I never thought it would be such a big difference. The shift points and lock up are perfect! You have done some amazing things with the mm3 tunes. I strongly recommend Rob’s tunes to anyone with a third gen Cummins. I had issues figuring out how to update the firmware and install the tunes and Rob helped me every step of the way. Can’t wait to hook up the fifth wheel on Monday and see how the tow tune behaves with 12,000lbs back there. Thanks again Rob!

“I got to pull the boat to the lake last weekend with the new tune and I can again say that it is about as good of a transmission tune as one could ask for. The up shifts and easy tip in down shifts are perfect. I’ve been pulling down 1.3 MPG better on all highway trips (hand calculate) and the power compared to stock is what this engine should have came from the factory with. The 1-2 shift is much better for towing but the 3rd gear lockup is when you really notice the difference…
I also have to give props on the fact that it actually smokes less now than it did before the tune!
My only performance mod is an S&B intake … high ram … and this tune.
“this transmission tuning rocks it is simply amazing how different it shifts and does what it supposed to do thanks Rob D” –
“I also have tuning from Rob D and I am extremely happy with the outcome…hit him up for your tuning needs!”
“If your truck has a 48RE, then you MUST, MUST, get Rob tune. It will save your tranny BIG TIME! I just replace my stock tranny due to heating climbing up a hill every day 7 mile steep. Sea level to 1400 elevation. Trans temp always 215+ plus degree. Andeven with a new stage 2 tranny with a deep pan and added trans cooler up front still would get up in the high 190-200* degree up this hill, I just installed Tow tune from Rob with his tranny tune set up , and man what a different. It shifts all in the right power ban, now it feels like a truck shifting. And now at the top of the hill my Temp was 170* degree -30 that fricken awesome!! I cant thank you enough Rob. So dont hesitate to PM Rob he will walk through the install, im not much of a computer guy,and thought i cant do this stuff. But just do you a favor save your $6K and keep your stock 48RE and get Robs tune. He not paying me for this, im just glad for his time & help. Keep making your tunes Rob im now a fan! 🤙”
