This is my first protune not my first etune and stratified has been amazing. Ke Xu has made that experience very easy and had an incredibly fast response time with any concerns or problems I had. Stratified has made my car come to life and really allows me to get the most out of all my performance mods. Finally on e30 and the etuning process was fun and easy.

I got a pro tune from them and I love it ! My tuner was fabrice and he was very patient with me and got me through everything, definitely recommend!

Customer service was great and I thoroughly enjoyed working together with my tuner on the tuning process. Fabrice listened to all of my input and adjusted the tune accordingly wherever needed. I was running a tune from a different company before and Stratified's beats theirs by a long shot. My car is now running smoother than it ever has and with even better performance than I expected. So glad I could have people as knowledgeable about my car's platform to work with on the tuning process, you guys rock!

Very happy with my car’s performance on my Stratified Pro Tune. I ran Stratified's flash tunes for years with no issues. When I eventually upgraded to a larger BNR 3071 turbo on my Focus ST I chose Stratified again to tune my car. Alex was able to exceed my expectations while providing very professional service. The wait times can be a bit longer than other tuners, but you can rest assured that you will be tuned by the most experienced tuner on the Focus ST platform.

After purchasing this tune and working with my tuner along the way was 100% worth it. Car runs solid and smooth and i owe it all to my tuner who was very helpful along the way. i appreciate all that was done!! I totally recommend Stratified for the best tuning process.

This is my third tune with Stratified Auto and after this tune of my new 2.3 high performance stroker in my focus st the car runs great no issues to report, the tuning process went great and Nolan Wang my tuner for all three tunes was very professional again and is awesome to work with.
