The whole tuning process was excellent! I have read the forums and know enough to be confused with it all, but the Stratified tune took all the worry out. My car was registering a lot of knock prior to the tune. All of the "knock" issues were worked out, and the car feels stronger from bottom to top. Alex is the man! If you don't believe me check out the Mazdaspeedforums.

Alex is one of the most knowledgeable Mazda tuners that I have ever met. I came to him when I realized my previous tune was not up to my standards. Once we got started with the tuning process, I knew I was going to be happy with my decision to go with Stratified. My car is safer, more drive-able, and finally up to my standards. I cannot recommend a tune by Stratified Automotive Controls any more highly!

I could not be happier with the way my car is tuned, mike did an awesome job with it and really helped me understand the process a lot better. He also worked with me with the issues I had with my car which he didn't have to do but I appreciate it a lot. Very happy with this tune.

The tuning process went very well even though there were some shortcomings on my end (fuel quality and hardware changes). Lex did his best to iron everything out and we ended up with a strong tune. Final VD shows 320/368 on Virtual Dyno without stressing the turbo too hard. Very nice tune.

My only suggestion would be to clarify

My tuner was Alex and he was the most professional person i have ever work with. When i sent him emails he replied back with me in a timely manor and i am extremily satisfied with my tune i have purchased for my Mazdaspeed3. I would recommend him to anyone that needs a tune.

After much research into tuning, I made the choice to go with stratified, and will NEVER look back. Alex has taken great care of my car and pushed it to a point i didn't think was possible. Once I went with a big turbo upgrade, there was ZERO hesitation on contacting Alex again, and he was more than happy to help me out. I recommend Stratified to everyone i can.
