I was running a Cobb Ots stage 2 & I purchased the E30 OTS and the difference is incredible, first pull on ethanol is insane, Day & night difference! Don’t sleep on this tune

Had a great experience working with Aaron the tune is great makes the car so much better, Aaron was very accommodating to all my needs and questions and I will definitely be a returning customer when I upgrade the car more.

I wouldn’t have bought this turbo from anywhere else I know stratified will make things right and will always have the right answers and feedback, it was shipped really fast and got my car tuned in a timely manor of perfection I will definitely be buying the rest of the parts for my build from them, thank you stratified team

Fabrice was very very helpful during the tuning process. Answered all of my questions related to my tune and got me dialed in exactly how i wanted! The car feels better than ever and is truly more fun to drive now. Will definitely be coming back when i go big turbo ;)

I worked with Aaron L to get a proper tune on my car with its new CTS KO4 Turbo. He did a fantastic Job dialing it in to make sure the boost curve was nice and smooth. Car feels amazing to daily drive and I cant wait to get it out to autocross. Always a great experience at Stratifed.

Jared did an incredible job with my revisions on my protune. After a reliable year with my last protune, I wanted to change the powerband to focus more on the top end power. Jared made this happen after a few revisions. Power on the low end is more tamed now for fuel economy as requested. I love having a stronger top end for better highway pulls. If you're looking to protune your GTI mk6, Stratified is reliable and pushes insane power. Customer service is A++++. Thank you again, Jared!
