We have been custom tuning GM gas vehicles and Ford gas and diesel trucks and cars with OEM experience since 1995 including all the Powerstroke diesels. We have owned and tested on our own vehicles, from the 7.3L to the all new 6.7L, supercharged Mustangs, and all F150s including the new F150 EcoBoost. We know what works and what doesn't. Don't settle for the other tuners who claim to know what they are doing but have never owned any of the vehicles that they sell products for. Don't be a tuning tester! Ask before you buy what experience the company has. We also offer export tuning for vehicles (including the heavy duty trucks - with Cummins and Navistar engines) going to other parts of the world with different fuel requirements - call for more details. Competition tuning and products are available for the true racer, call for details.

2015 Ford SuperDuty 6.7L tuners and tuning now available on SCT X4 and Livewire TS products!

KEM

We have been tuning the 6.7L longer than any other company and know what works and what doesn't. The tuner comes with 3 power levels: Tow, Performance, and our RACE DPF ON All-Out file. Please Note: These are on highway use files only! It will require that all of the emissions equipment is installed and operational on the truck. Attempting to use this on a deleted truck will cause issues! We recommend that your truck have the latest Ford flash for best tuning operation and the most power.

After ordering, you will need to send an email with the VIN, engine and transmission strategies, and all mods done to the truck.
