I had my car tuned by Alex at Stratified and am very pleased with the outcome. My car drives great and any questions I had were answered fairly promptly. While I wasn't satisfied with the resulting power of my initial setup due to poor fuel quality in my area, they quickly got a water meth injection setup shipped to me and were more than fair in what they charged for the continuation of the tune with a hardware change. I'd highly recommend them and can foresee using them again in the future for my next vehicle!

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
