Product Info

Compatible with:

Cummins 2003-2004
Product Description

SOTF Tunes will only work on 2004+ Trucks. If you have a 98-03 you can only run a SINGLE TUNE.  

These are custom tune files for your MM3 Device! These are some of the best custom tune files on the market for the Cummins. Diesel Techs writes each tune specifically for your truck and its modifications. These can be customized to suit any setup, whether it's a twin-turbo race truck or a daily driven tow rig, these are the best on the market. 

If you want a single tune, choose one from the list, or let us know the type of tune you're looking for. If you want all the tunes, no input is needed, just let us know the current modifications done to your truck.

Customer testimonials

Don't just take our word for it...

Everything turned out great and my fuel mileage has increased dramatically. My truck has more power even which my SoFT is in the 1 position.

Excellent service. Thank you

Ron

03-07 Ford SCT Tuner & Tunes

Extremely happy!!! Thanks to your quick shipping and great products my Duramax is alive and well again! No longer in limp mode and running perfect with the first of 5 tune levels. Once I upgrade the fuel pump, I can't wait to see how it runs at the dragstrip with the higher HP tunes. Install of the exhaust components and the SOTF switch was very easy, done in under 3 hours total. The EFILive loading was also easy and the full tune yploaded to my truck in less than 10 minutes. Thanks for amazing customer service and excellent quality! The Diesl Techs is now my go to for all things Duramax. I have already spread the word amongst my friends and some fellow diesel enthusiasts, and will be sure to continue recommending Unlimited.
