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!!

Alex is very talented and it's so clear he's passionate about what he does. Every detail matters, nothing is overlooked. He was very helpful in getting my car running healthy and the car is running great now! Amazing customer service, many tune revisions made and many more to be made I'm sure, but Alex is always ready to help and is so knowledgeable and friendly. 10/10

Stratified is the ONLY way to go for the mk6 GTI. Clayton was a huge help with getting things sorted for the tune. This tune breaths new life into the car and I cannot wait to continue pushing it further.
