Stratified completely delivered the best possible tune for my 2017 Golf R with a CTS Boss600 turbo kit(GTX3071R), on a stock fuel system. Alex G was able to extract every once of power possible from the setup, while maintaining civilized behavior, when driving around normally. Was averaging around 26+ mpg in the city, with light traffic. When opening things up, the power delivery is unreal. Car makes power through the entire RPM range, and will continue pulling up top. Maximum torque seems to come on around 4500+ rpm and gives you a nice shove into the driver's seat. Communication throughout the entire process of remote tuning was an absolute pleasure. Alex was extremely attentive, knowledgeable, and an all around pleasure to communicate with. He's a true perfectionist that won't stop until things are dialed in perfectly, and exceeding expectations on the logs. If you were on the fence about getting your car pro tuned, it's time you hop off and go all in with Stratified!

Alex did a great job with my 2017 WRX. He was quick to respond and when I ran in to some problems he help me solve them and adjust my car to the perfect tune. My car runs so smooth now. I would highly suggest Alex when it comes to tunning your car.

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!

The tune is fantastic, power delivery is incredible, was everything I wanted and then some.

Response to emails when sending logs is perhaps bit slower than I'd like (typically 1-2 weeks), but not too bad. Alex addressed everything I needed, and when I added a crackle tune on he delivered a map where the crackles only happened in sport mode, which is awesome, and something I didn't think would be possible.

Overall highly recommend over APR, the ability to flash and revise maps yourself, and the added function of having the COBB accessport is a huge plus to me.

Response time is very efficiently and both people who have helped me have very friendly and helpful about tuning questions as well as answers for future plans, as for the tune itself it’s very good usually get no knock and pulls strongly

I got tuned for FBO aux fuel 93 and E50 and I couldn’t have asked for a better tune. Best tuners out there for the focus platform, I have tried other tuners and they don’t compare.
