They work with you to get the tune "you" want. Very helpful, and a great knowledge of the Speed3 engine. The tune came out better than I expected!

If I could give more stars I would! My car feels like a completely new beast! I didn't think much could be pulled out of the car but the E85 tune that Stan set me up with it's a night and day difference. I really appreciate Stan working with me since my car had to be sent back to the shop during our tuning process. The whole process was truly a great experience and I will definitely be back for another tune in the future. Thanks again!

I recently had my 2007 speed3 tuned by Alex. The car runs flawlessly, and he was very quick to point out any issues that he saw during the process, and diagnose the action that needed to be taken. The boost comes on smooth, and stays that way right up to redline. Tuning with Stratified could not be any easier. If you can drive your car and run the accessport, you will do fine. I would do it again, and highly recommend them.

A big thanks to Alejandro Buse and Stratified for the custom tune on my Mazda 3 MPS. Alejandro was great to work with and took the time to answer all my questions very thoroughly. He was also very patient and helpful while we dealt with some inconsistent fuel quality. We achieved some excellent results despite my only power modifications being an intake and HPFP upgrade. Highly recommended to any MPS / Mazdaspeed3 owners no matter where you are in the world!

What can I say that everyone else hasn't said. Alex truly is a great and knowledgeable tuner. The tunes he is able to produce are quite remarkable and mind blowing. He has completely transformed my car from a nice daily driver, to the Hulk on steroids.... If anyone is still hesitant on using Stratifed Tuning as their tuner, don't. They are very professional and drama free. They will explain every new tune and steps needed to turn your ride into your dream ride. Thanks again for everything Alex! You're truly one of the best hands down!

Once again stratified tuning left me speechless. I have to say the customer services is just awesome. I always had the feeling that I was under good hands. I have never had a problem and don't think I ever will. Alex takes every tune personally and I have to say it shows it. Every time I had a question alex answered it with complete detail so I could understand it. I do consider alex a wizard in the mazdaspeed world even if he doesn't believe it. I will be coming back when I get more upgrades. Thanx alex. 100% awesome.
