Alex is very talented and it's so clear he's passionate about what he does. Every detail matters, nothing is overlooked. He was very helpful in getting my car running healthy and the car is running great now! Amazing customer service, many tune revisions made and many more to be made I'm sure, but Alex is always ready to help and is so knowledgeable and friendly. 10/10

Stratified is the ONLY way to go for the mk6 GTI. Clayton was a huge help with getting things sorted for the tune. This tune breaths new life into the car and I cannot wait to continue pushing it further.

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 !
