    The entire ProTune process was simple and enjoyable. John D. helped me dial in my CTS K04 and was incredibly patient with me even though I wasn't able to get data logs done quickly due to my schedule. Each iteration of the tune was more refined than the previous one, and it was really fun to experience the incremental improvements.

    Would definitely recommend the Stratified ProTune to anyone looking for a simple and enjoyable experience!

    Tuning was smooth and easy. Car feels better than it ever has. I was able to choose exactly how I wanted the tune to be. I can’t recommend it enough.

    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.
