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.

Once I started working with Stratified, specifically Stan, It was easy to see their dedication to the customers, providing the best possible power and drivability for our vehicles. Stan went through extraordinary efforts during our tuning process to make sure I was getting the best and safest power outputs at all times. During the tuning process I was always informed and educated of what was going on, why we made changes what we’d work on correcting in the next steps and how it’ll impact the vehicle.

Stratified did wonders to my speed3 and I couldn’t be happier with the result and the process that created it. I highly recommend Stratified for any tuning needs.

Dealing with Stratified (Alejandro Buse) has been a great experience. I have learned a lot about my car and its capabilities/wants/needs and am excited to put my newly empowered ride to the test. I track regularly and just finished my tune and am 3 weeks out from seeing what this tune will do for my times.

The turn around time was prompt every time. I sent logs and would have new maps within a day, sometimes 2; but never longer.

I asked questions, some good ones, some dumb ones and was never given anything but a respectful informative response.

I would give these guys more that 5 stars if it were an option. My car, under its current build, has entered beast mode thanks to Stratified and Alejandro.

Sincerely,
Struggling for traction in 3rd =p
