The tuning process with Stratified has been amazing. The turn around time for data logs was always fast and they turned my car into a whole different monster. Also the customer service has been amazing in helping diagnose any problems or questions I needed answered.

The entire process from start to finish has been amazing. Everything from the customer service from everyone I have talked to, to the tunes and customization of them. Even with my big turbo GTX2867R, the car drives much better than stock. The refinement and drivability are fantastic. During my tuning process I could feel every tune revision adding power, adding more refinement to everything from the way the clutch engages to the how boost builds up. The car pulls hard. Overall the tuning experience was more than I could have ever asked for. I will continue to use Stratified for all of my tuning needs.

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.
