This is the tuner you need and no one else! Simply the best and Alex works with you with all the hiccups along the way while tuning which is just simply awesome in my books! He was able to put down the power and reach my goals and maximizing my mods to its full potential. I called around my city for a local tuner, the tuners here had to basically use my car as a test mule cuz they never have tuned a mazdaspeed before so I said forget that, took the chance of a e-tune and let me tell you, simply THE BEST. I honestly wouldn't even bother with any local tuners after working with Alex. I have done over 25 pulls while tuning and not one issue. DO it people!

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!

Just completed a tune for both 91 and 25% E85 blend for my 06 MS6 with the master tuner, Big Stan. Stratified was truly excellent and accommodating. During the tune we discovered that my autotech HPFP internals were failing. Guys at Stratified were completely understanding and able to work with me until replacement was sent and reinstalled. Big Stan was also able to eliminate large amounts of KR (despite the poor 91 here), fuel cut, and even identify a small leak at the turbo inlet to TIP! The ENTIRE tuning experience was great, smooth, with quick correspondence and professionalism. When I finally add a few more hard parts Stratified will be my only choice for e-tuning! If you have any doubts utilizing E85, do not. It is essentially 1/4 price race fuel available at the pump. My car is significantly more responsive, powerful and not to mention safe! Thanks again Big Stan and Stratified.

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.
