Took care of everything needed in a timely manner. Only heard good things and I’ve just finished my tuning process and am beyond pleased. 10/10 recommend to anyone looking for a tuner.

i had a great experience working with Fabrice, walked me through everything and response time was fast. i'm extremely satisfied with the custom tune, will definitely come back once i upgrade more things.

My experience with Jared was great. The communication was there always responding to my emails/questions in a timely manner. The man hooked me up with a solid tune. My cars been running flawlessly since my 2867r turbo upgrade. Very pleased!

The overall process was great! I was a bit nervous at the beginning as my 2013 ST has 70k miles on it with a BT setup. I was looking for a safe daily tune with the addition of the aux fuel. I went in knowing that it would take some time doing remote tuning but it was worth the wait. We did a new base 93 tune, E30, 93+ aux fuel, and E30 + aux fuel. The end result was 373whp on the stock block. All of my questions and requests were met in a timely manner, also the rough idol the car had was corrected. The Aux fuel setup went very smoothly and makes for quite a bit more fun! I did learn a few new things to watch and got a better feel for how the car handles with each new tune. It's an experience that a dyno tune doesn't quite give. My prior tune was a dyno tune from a reputable shop, but this tune actually produced less knock and a bit more power (I was at 325whp). They also helped reign in the wheel spin to a more manageable level. Once we build the engine I'll definitely be back for new tunes! I feel like Stratified gave me a new car!

Love the tune on my ‘14 focus ST. It was a great experience working with Fabrice Vieillesse. Always quick and happy to answer all the questions i had during the process. More than just custom tuning the car, the Stratified team also helped me gain a more in depth understanding of the ford ecoboost engine, what to look for on logs to make sure the tune is responding properly, and what the car is capable of.

The tuning process went way smoother then I expected thanks to my calibrator it was professional from beginning to end and OMG my focus st runs great !!!! I will definitely be back for my power upgrades thanks Stratified ...
