Stratified is absolutely fantastic. If you look around on various forums they have a reputation for quality and it is very well deserved. Excellent power without sacrificing driveability. Since this is the first car I've done any modifying to I was a bit paranoid at times, but Aaron addressed any concerns or questions I had. It's also fun to experience the changes with each revision and look at the differences in datalogs if that interests you. I will definitely be coming back to Stratified after I do more modifications.

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
