2007-2013 Mazdaspeed3 Pro Tune
[MS3_ProTune]

If you have any doubt about getting a stratified tune, let me remove it for you. My speed is fully bolted, but this gave me the most noticeable increase in performance by far. I was pretty happy with the car's power, but the tune transformed it into an entirely different animal. The turbo pulls like a freight train all the way to red line, much harder than I thought was possible within the limits of the k04. Brad and Alex were a pleasure to work with. They were able to give me revised maps as fast as I could send them the logs, and explain the tweaks they were making along the way. You will not be disappointed, the stratified crew truly does great work!
