The tune is great, more power no less of driveability and the mpg remained the same. It's nice having a pro tune for your area and gas. It's also great to have a professional look at the numbers and make sure everything is good to go. Thank you Stratified!

The tuning process was very well explained and everything went very smoothly. I highly recommend getting your car tune by the Stratified team if you can. I had my car tuned by another company before and the Stratified tune is so much better power wise (94 octane tune). Don't hesitate and get yourself a tune !

Purchased this custom tune after hearing great things about Stratified from the Mazdaspeed forums. Was not disappointed! The tuner was professional and thorough, and the tune totally woke the car up. I would absolutely go to Stratified for custom tunes in the future!

Got the e30 tune w/o the high torque option for my 15 ST, and it runs so goddamn smooth! The difference in power is really eye-opening and second gear is almost useless already, even with the torque limiter. Temps are good even with stock fmic and my AP seems to indicate there's plenty of room for more perfomance even though I'm already satisfied with my car. Would definitely recommend

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

GOt my 2017 GOLF R tune by stratified(added the crackle). If was a pleasure working with Alex. Kept me inform if I needed to change anything. During the process of the tune, there were places where I found the car running weak. I let Alex know, and e quickly fixed it up. Discuss my future plans with him, and adviced me how I can reach my goals. Will get another tune from him within 2 weeks for my Big turbo. TOp notch service, excellent experience, and was very patient with how big of a noob I was!!

If you guys are on the fence, give them a try. Great service and turn around time.
