Shelby 2010-2014 Tuning Hptuners

Did you change your upper pulley? Maybe you did headers or exhaust? 

We are taking you from stock to a level 10 driving experience. 

Our engineers have over 15 years of experience in Ford and Shelby vehicles and have gotten great results after tuning a mildly modified vehicle. 

The best bang for buck mod on this platform is upgrading the upper pulley to a smaller one and then tuning to make sure the throttle is not closing or robbing you of any horsepower. 

On 93 octane these engines with pulley only will do 640hp. 

All you need is Hptuners MPVI3 which is available before and credits.

We give you detailed instructions on how to read your factory file and the best practices when flashing and logging your Shelby vehicle
