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.

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.

This is the best bang for your buck. I was hesitant at first cause I've never done any kind of E-Tuning, but Alex was great at explaining everything to me. Alex is a straight up genius to this tuning stuff. If anyone is hesitant in doing an E-Tune, don't be. Stratified Tuning will definitely take care of you through out the entire process. So buy an E-tune from Stratified now!
