I would suggest stratified to anyone looking for an amazing tune. Even though it is an etune the tuner assigned to you takes a serious personal interest. I got my tune within a few hours and even after that any questions I sent or adjustment I needed the tuner would make them and send me the new map within an hour or two. The tuner also had helpful suggestions and was really knowledgeable. I can not believe the fast response and amazing service. And that's all before I talk about the tune! Coming from stage 1 cobb tune right from accessport v300 93 Oct I thought the stratified tune would be minor upgrade since I needed something to support my catless downpipe so figured I use this. But it was beyond what I thought it would do. Stratified tune is more powerful, smoother, etc. Shifting now is extremely smooth the rpm drop is perfect, turbo spools instantly, engine response is better. Plus launch control is awesome. The ability to switch tunes while driving is another great feature so if I am on parkway can run Eco then if someone pulls up can switch on fly. I also never used a car with flat foot shifting and it's pretty damn cool I was nervous at first but now doing hard pulls can't do without it.thanks again and will come back for future tuning needs.

Excellent service from Alejandro Buse. Extremely patient, answered and explained all questions I had clearly. Will definitely recommend their service and be a returning customer again in the future.

Once again stratified tuning left me speechless. I have to say the customer services is just awesome. I always had the feeling that I was under good hands. I have never had a problem and don't think I ever will. Alex takes every tune personally and I have to say it shows it. Every time I had a question alex answered it with complete detail so I could understand it. I do consider alex a wizard in the mazdaspeed world even if he doesn't believe it. I will be coming back when I get more upgrades. Thanx alex. 100% awesome.

Once I started working with Stratified, specifically Stan, It was easy to see their dedication to the customers, providing the best possible power and drivability for our vehicles. Stan went through extraordinary efforts during our tuning process to make sure I was getting the best and safest power outputs at all times. During the tuning process I was always informed and educated of what was going on, why we made changes what we’d work on correcting in the next steps and how it’ll impact the vehicle.

Stratified did wonders to my speed3 and I couldn’t be happier with the result and the process that created it. I highly recommend Stratified for any tuning needs.

Dealing with Stratified (Alejandro Buse) has been a great experience. I have learned a lot about my car and its capabilities/wants/needs and am excited to put my newly empowered ride to the test. I track regularly and just finished my tune and am 3 weeks out from seeing what this tune will do for my times.

The turn around time was prompt every time. I sent logs and would have new maps within a day, sometimes 2; but never longer.

I asked questions, some good ones, some dumb ones and was never given anything but a respectful informative response.

I would give these guys more that 5 stars if it were an option. My car, under its current build, has entered beast mode thanks to Stratified and Alejandro.

Sincerely,
Struggling for traction in 3rd =p

Well the custom tune or "product" is really the experience of these guys, Mike in my case. Very helpful, took on board my queries, gave advice and proceeded the tune in a safe manner. When you give someone almost free rein to play with your car it could be a bit daunting but not in this case! Also being involved in the process, as in doing the actual logs makes it a better experience in my view. Highly recommend anyone who is thinking of doing this to get in touch with them. Very satisfied customer cheers!
