I had a great experience with Clayton and the ProTune! It was a lot of fun and instantly took my car to the next level with my current mods. Highly recommend!

Alex is an outstanding car tuner who recently performed an E30 tune on my vehicle. Not only did he enhance the car’s performance significantly, but he also went above and beyond by identifying an issue with the MAF sensor and assisting me in resolving it. Thanks to his expertise, the car now drives better than ever, and I truly enjoy the improved performance. Highly recommended!

the best experience in tuning your mk6, the communication with my tuner John D. was immediate and we understood each other very well, this option is excellent to get the best out of your GTI

Hello, I have a 2018 focus st. I worked with Ke Xu, he did an awesome job. At first when I did the install and added the first map I was underwhelmed, I thought I made a big mistake. However after working with Ke, thirteen maps later he got it dialed in. The care runs AWESOME! I could not be happier with the results. I can't wait to get to the dyno and the track.
A BIG THANKS TO STRATIFIED TUNING AND KE !

I think I was one of the first to sign up for a GR Corolla tune as soon as Alex offered them. Each iteration was a step up from the previous tune with the final tune being perfection! More power everywhere! The car feels so much different than stock and is much more enjoyable to drive. I highly recommend Stratified if you wan to add some juice to your GR.

Very experienced tuner!! Super happy!! I have been building cars all my life and can say these guys 100% know what they are doing!!
