I have a positive experience with my tuner Aaron. He takes time to explain and the turn around time is reasonable. I am able to get most out of my current mods in a safe delivery with excellent drivability which is essential for a DD. The Stratified crackle tune is a big plus if you want more noise, it is more subdue than few other tunes which gets annoying at times.

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.
