Performance Chips & Programmers

This calibrator worked. I tried the factory tire sizes at first, that didn't work. I measured both sets of tires that worked perfectly. directions and customer service were great. View more reviews...

18 Mustang Ecoboost A10 with performance package and wagner evo1 intercooler. definitely woke up the car it pulls harder and higher into the rpm band. shifts are butter smooth in drive mode and feel firm and deliberate in sport. tire size adjustment is a good plus. View more reviews...

This is a great programmer that is very easy to use. I do suggest setting up your programmer with updates at your pc first it saves time. The only reason I say this is the updates take some time. As for custom tunes that download those are good and I have not changed anything for the stock updates. It would be nice to have better understanding on what you can change in your tune in the prompts and what that may do for your truck. Just a suggestion View more reviews...
