My tuner Fabrice was awesome during this process, he answered any questions i had and always kept me up to date. Will be coming back again when I get my big turbo. Thank you guys!

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.
