I offer Free Tune updates for 1 year after purchase. These updates usually address drivability issues or other small problems found by me or a customer. To receive an update, please use this form to contact me.

Latest Tune Updates:

8-3-2019: Disabled hidden pre-injection events on 12 valve tunes creating the only “True” 12 Valve Tune on the market. 2004-2005 Trucks can now use the Tow Haul shift schedule AND keep the OD Off button like the 2006-2007 trucks already have.

6-7-2019: Improved pre and main injection timing values for the tow tune.

5-19-2019: Improved wastegate settings in all tunes and applied a very much improved 48RE 4th gear shift map to all tunes.
