I contacted Alex about a custome tune for my MK3 Focus RS and from start to finish the whole experience has been nothing short of excellent. Alex was always able to advise and saved me spending money on components he has already tested and seen no improvements with. The stratified map has transformed a good car into something great. This car has so much potential and Alex has definitely unlocked that potential from the bolt on’s I have installed. I look forward to working with Alex again in the future when I decide to take the car to the next stage. Would highly recommend to anyone to try one of these custom maps.

Thanks David

Alex did a great job of dialing in an E30 tune for my billet compressor wheel - modified stock turbo and actuator (Otherwise Stage 3) on my 2017 Focus ST. This was a non-standard setup, so we had to do quite a bit of "dialing in" Alex was very methodical and we arrived at a great tune. I'll post up before/after dyno plots once a do the "after"

2014 Focus ST EFR 6258 custom tune.

Fantastic work, very helpful and knowledgeable. My tune was a bit more work than most since we were looking for the sweet spot of ethanol on the stock fuel system on a larger and somewhat uncommon turbo, but Cyrus was patient and courteous every step of the way. Car makes safe linear power now and the Stratified traction control is like magic. I will 100% recommend Stratified to anyone looking for a safe, detailed tune.

After working with Alex on my pro-tune I cannot say enough how great of an experience it was. They made it a top priority that my car remain drive-able and safe along with providing the most power we could get. It was very clear that they take every pro-tune seriously and make sure you are completely satisfied. I couldn't be happier with my choice to go with Stratified and would recommend them to anyone looking to upgrade their ride.

I would like to thank Stratified for an amazing tuning experience. They really know their stuff! I work two jobs and have a busy schedule but they were very patient with me during the tuning experience. Cyrus has my car running amazing and the difference is night and day. Especially the E30 tune! Turned my Fiesta ST into a little rocket! Again, thank you Stratified for your excellent work and continued support. Keep making things go faster!!!!

After Christmas I had the opportunity to go Stage 3 on my 2014 Ford Focus ST and have received my final revision for my 91 and E30 custom tunes from Stratified. I could not be happier with the result. Cyrus worked his magic and tuned the car to my specifications of increasing power while maintaining the reliability of a daily driver. I am a member of the AZ ST Club out here and Arizona and was able to drive a Stage 3 ST with a Stratified Flash Tune prior to purchasing this one, however I had not driven one that was custom tuned. After driving both now, I would highly recommend spending the money on the Custom Tune. Cyrus noticed some abnormalities in my datalogs that were caused by poor fuel quality (Chevron 91 Octane, Common issue in AZ) which would not have been noticed with the flash tune. For those interested, my car, on the E30 tune, was putting out a healthy 290 HP and 360 lb/ft of torque to the front wheels. Overall, I do highly recommend the Custom Tune and look forward to coming to stratified for any future endeavors!
