I just finished up with the MAF calibration process after flash tuning my FA WRX. Stratified and Clayton exceeded my expectations in every way with the experience and results. Clayton was receptive to everything that I was looking for and was quick to point out some parameters that could be improved on. My car now drives better than I could have imagined. I can feel a drastic difference in power through the entire RPM range. The power feels smooth and consistent and the car no longer wants to fall flat after 4k RPM or like it’s held back by its own weight between shifts. It also feels like it’s operating within safer parameters, which is critical for me because I drive the car most days. I really can’t say enough good things about Stratified Automotive Controls and Clayton.

Definitely a massive difference from the normal crackle tune going to this one. Much more loud pops and barely any burbles. I shoot flames with this tune, but that’s mainly because I have the aux fuel kit running E30 in mine to give it more juice. If you want super loud, definitely get this option.

I can send videos of how it sounds.

Tuning with stratified was very easy and definitely worth it. Clayton was my tuner and he was very nice and helpful with my questions and requests during the tuning process.

My car has a K04X with stratified extra fuel 5th injector on E30… of course with a ton of supporting mods as well and it feels very good with the tune. At first after installing the new turbo it was all over the place with boost and power, but after a good while tuning it through datalogs, it now is super smooth and fast for this turbo while keeping the knock very minimal.

Got 91 Maps and E30 Maps for the car. Definitely recommend this tune and going through the tuning process because it’s fun seeing the car get faster and better over the time of tuning it. Glad I went with stratified. No dyno numbers yet, gonna do that in a few weeks. Later this year I’m going big turbo boss600 and going to get tuned through stratified for that aswell.

Did their custom flash tune with the datalog refinement and I couldn’t be happier with the experience. They went above and beyond to get the setup dialed and were so speedy and responsive. Would absolutely do it again

Customer from germany here. Got my Big Turbo Focus ST Mk3.5 tuned by Ke Xu. Really love the tune and the way the car performs now. Ke Xu responded really fast everytime. I reached my power goals and got a reliable tune aswell. Would recommend this protune anytime.

I purchased a tune for my focus RS and Ke Xu was the technician that assisted me throughout the entire process. He was very helpful and prompt on any questions I had. My car feels totally different with the tune! Thank you Ke Xu!!
