Alex did great. I would highly recommend Stratified tuning services to anyone who is looking for a custom tune. They will get you every HP possible, but they will still keep the motor safe and happy. We were able to reach my HP goal, but because of some limiting factors, we had to utilize E85, which was fine with me. Its nice knowing that i can drive my car and not have to worry about anything going wrong. Thanks for the great tune and awesome customer service!!

The process could not be easier. The end result is power gains throughout the whole rev range and smooth at that. Alex was fantastic in answering all my questions and helping through the modding game. Would I go through this process again? Yes yes yes.

From start to finish, with each map, the car felt better and better.
Each map modification was done so carefully and meticulously, to ensure the safety of the engine with maximum performance. Alex knows whats best!

Professorial assistant and very good tuning, not only better map, but also made the car feel much better and a whole better throttle response.
Very happy! I Highly recommend

Working with Alex at Stratified to produce a custom tune for my 6MPS has been immensely rewarding and satisfying. I now have a custom tune, based on real-world driving conditions, for about a quarter of the cost of a dyno tune in Australia.

In combination with VersaTune, my car now takes full advantage of its mods, it's more efficient, and the hesitation and other quirkiness of the stock tune has been eliminated.

And the customer service was exceptional. Professional, knowledgeable, safe, prompt. Alex wasn't happy until I was happy. Thank you Alex.

When I contacted Stratified Tuning I was looking for a tune that would take advantage of the mods I have on the car but not be so aggressive that my car would be in danger. That's exactly what I have after the tuning process. From the first revision to the last when we finished the car improved in exactly the ways I was hoping; it is faster than when we started and the tune doesn't have the danger of the stock tune. All in all I'm very happy I picked Stratified Tuning and I'd recommend it to any other Mazdaspeed owners out there.
