It's crazy how much of a difference this map is vs the AP maps. I'm running stg 2 93+ and its unbelievable the difference. Not only does stratified offer such great ots maps but every single question i have sent has been answered in less than 24 hours. Very professional and just the customer service alone impresses me. Great job stratified! I look forward to my Full custom tune on my MS3!!

I recently had Stratified tune my Mazdaspeed6. The car now runs much better and makes more power than I had anticipated. Alex was very professional and made the process easy. He was always happy to answer any questions I had, and kept me informed of the changes he was making with each revision. I could not be happier with the results!

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.

After countless reviews read trying to find something not already hit on, I came to find out there was none. Alex is just simply amazing. Having a couple issues arise during the tuning process he was more than willing to work with me as I worked out the kinks on my end. He showed that he truly cares and you are not just some P.O. number. As for the tune, I could not be happier.The powers linear delivery makes for great driveabily. Knowing you have the ability to leisurely drive around the city or open it up and tear down the streets is a far improvement over a tune from another highly rated tuner. I highly recommend Alex to anyone considering going with a tune. I point not just to reviews of here but to forums where Alex has helped numerous people without asking for anything ins return. I look forward to my future e85 tuning and knowing I put my cars future in the most capable of hands.

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!
