the tuning process was simple and easy, and compared to the tune i alredady had through a local shop i gained quite a bit of power on both my 93 and E-85 maps. the car feels the best it ever has and its enjoyable to drive day after day. im looking foward to more modifications to my car so i can come back to Lex and get even more power out of my car. Great company with Great results!

I was tuned by Mike at Stratified and we started with e-tuning and then went to in person, dyno tuning. Turned out my spark plugs weren't gapped (at all lol), so Mike helped me correct this problem and then the tuning got started. I am extremely happy with the new custom tune and all the stuff I've learned from Mike as I'm new to the Mazda platform. I really like how Mike explains stuff and communicates with me. I highly recommend Stratified!!

I just installed a gt3071r turbo and a water/meth kit. After Alex got done tuning my car is making 359hp and 361lbft torque at the wheels!!! Its accelerates very hard and smooth at the same time. Alex even helped me figure out some problems I had with the hardware that I installed. Really worth the cost of the tune!!! I recommend Stratified to everyone I know with a mazdaspeed! I'll be back in the future after I done more mods. Great job Alex!

Just wanted to say I had a great tuning experience with Mike at Stratified. The car feels great. What a night and day diffence between Mikes tune and the OTS map. I will surely be coming back to Statified for all my tuning needs. Maps were delivered quickly back to me and Mike answered all my questions. Thanks again for all the help. Keep up all the good work.

Very impressed with the service provided. Alex was always there to answer my questions and guide me throw the whole process. Will recommend to everyone.
Keep the good work.

I bought this product having never tuned a car in my life. I was surprised to see how easy and how well Stratified explained the process of the tune. Stratified fits the tune to your preferences and how you want the car set up. The tuners are very easy to work with and are forgiving about time limits. This tune will increase power and reliability of your car. Overall this tune was very easy and not stressful to do and is totally worth it for the money and the fun.
