I can’t say enough good things about Stratified and my tuner, Alex. He is by far the most knowledgeable person I’ve dealt with on the MazdaSpeed platform. He has unleashed the true potential of my vehicle and I praise him every time I bury my foot into the throttle. One thing that was clear during this tune, Stratified is more concerned with helping and pleasing their customers than the money that is generated from it. I could not have asked for a better tuning experience and am looking forward to my next tune from Alex. E85…. Meth…. Big Turbo…. I can see all of these in my future, and Stratified will be right there with them!

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!!

What a absolute pleasure it was working with Alex on a custom tune for my car!
Not only did he do a excellent tune that was way safer and stronger than the Cobb tune I had before but I learned so much about the tuning process that I didn't know about before. So now there is at least one Stratified tuned Mazdaspeed6 in Sweden with a very satisfied driver.

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.
