I got two maps from this service and all I have to say is that my tires are wrecked. So much power that they just can't hold up. But in all seriousness, Alex is a great guy and great tuner and I wouldn't recommend any other tuner. He was quick to respond, knowledgable about the platform, and very understanding of how busy I always was. I'm a dorming college student and so I don't always have much time or opportunity to drive around much but Alex was very understanding.

If you guys want the best tuner out there for the Mazdaspeed 3, look no further. Stratified Auto is the best and I wouldn't ever think of getting tuned anywhere else. So just make the right decision already!

I had my 2013 Mazdaspeed tuned by Mike and am pleased with how the car turned out. I went for a 93 octane e-tune and after a while decided I'd rather have the tune performed on a dyno since I live in the same area as Mike. Mike went out of his way both to perform the tune in person as well as to explain everything that was being changed and how it affected the overall tune. I could not be happier with the experience and highly recommend Stratified custom tuning!

Did a 91 and e85 tune with Alex. He is a true professional. The results from both tunes far surpass my meager attempts at self tuning. Unless you are willing to devote days to mastering the DISI platform, it is a solid investment to have Stratified tune your car instead. Power delivery is fantastic and overall drivability is great. I could not be more pleased.

I can't be happier with the custom 91/E85 tune from Alex. It feels like a completely different car now, so much more alive and responsive. You can bet that I'll return when I go to a bigger turbo. Thanks again Alex.

IMPRESSED! That is the single word that comes to mind when I think about the result of my Stratified Tune, not only is the power abundant but once it comes on it stays on till redline and never sounds off, AMAZING! Alex did a great job and I will be coming back for an e85 tune in the spring and again in the near future for a bnrS3 tune. 5 Stars all the way, go with Stratified and you will not be disappointed, money very well spent.

Best money spent so far. Alex was a huge help and really knows what he is doing. We went through 10 different maps to get it so it's right where it should be. Even with the bad California gas I have to deal with the tune came out great. Feels faster and smoother in the power delivery. I also bought the Guardian angel for peace of mind and it was simple to install and also works great. I would recommend this company as a whole to anyone who wants quality parts and friendly and knowledgeable staff.
Thank you again.
