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.

i got a stage 1 tune just to drive around untill i sell the car, im very impressed , strong and very smooth tune

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.

I have a manual swapped 2011 gti and after I got the tune I was encountering rev limiter issues so I emailed back and they got it fixed right away for me. The tune runs great and the car feels way better than on any of the Cobb maps.

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.

I have a '14 Ford Focus St currently at 77k miles. I have been Stratified tuned since 5k. Just recently went big turbo and obviously needed an updated tune to match. I did a custom tune with Fabrice and the outcome exceeded my expectations. Customer service was great, communication was great. Would certainly recommend!
