Easily the best upgrade for this platform. From the first flash you could feel the potential this car has. Final flash you can definitely feel the difference. This is how the car should have come from the factory.

There's a reason why Stratified is highly recommended in the tuning community. I recently went big turbo on my Focus ST along with tons of supporting mods, but no built engine. I explained my goals of having safe and reliable power, and longevity given the age of my car. Ke was patient, helpful, and gave excellent guidance to help me meet my needs. He even helped me understand the safety and reliability of upgrading my injectors and high pressure fuel pump. After multiple months of back and forth (mostly due to me installing mods, and needing time off and good weather to safely do pulls and logs), we got my car to an awesome performance state. Mods: GTX2867R II, Focus RS OEM injectors, XDI Evo HPFP, CAI, catted downpipe, AWE Touring resonated exhaust, E40. Ke has informed I should be slightly above 400 whp. Can't wait to get my car dyno'ed to see how much I'm actually making. Thanks Ke for your hard work, and vast knowledge. This has been a wonderful tuning experience, and I highly recommend you consider Stratified for your next tune. Ke kicks butt and knows his stuff.

Absolutely amazing tuning service from Ke & super fast turnarounds for new revisions for each tune adjustment! Car feels completely different and I feel incredibly confident in its overall performance thanks to his incredible tuning experience.

Clayton did an awesome job tuning my 2011 MK6 GTI running a CTS K0-4X hybrid turbo. He was patient, answered every question I had, and was excellent with communicating throughout the process.

4 port controller for mk6 GTI. This kit is fantastic! Installs the same way as the single port, just with the provisions for 4 injectors. I’d recommend doing the flex fuel option for the controller itself. It’ll only be flex for the extra injectors. But makes life easier when switching fuels. Overall fantastic, love the final product.

Just finished my last revision with Alex, the process was easy and timely. I tried a protune with another company but the response time was not very good or communicative. We did a flex tune starting with terrible California 91 up to E75 which is what I could get at the pump. Since the first file the vehicle already felt much better than my previous tune. Alex answered every single question I had almost immediately and even helped me diagnose some non tune related issues that I had. Overall I am very happy with the service, from start to finish it was a real pleasure. My car feels like a completely different car now, daily drivability is maintained. When in race mode my car is an absolute beast. Definitely recommend Stratified over the other one we all know about.
