Purchased this custom tune after hearing great things about Stratified from the Mazdaspeed forums. Was not disappointed! The tuner was professional and thorough, and the tune totally woke the car up. I would absolutely go to Stratified for custom tunes in the future!

The tune I got from stratefied is simply amazing. My car pulls harder in every gear and is much faster and smoother. I highly recommend them to anyone that wants to get the most out of their car. Now to go get on a dyno.

Cyrus was the one who tuned my Mazdaspeed 3. We did a E30 mixture tune and I could not be anymore happy with the car. He did a fantastic job with the tune, it is smooth, VERY powerful and perfect for everyday use. He answered every question I had to ask and VERY patient with me when I had to car down for about 2-3 weeks during the tuning process due to my local mechanic plumbing my EBCS incorrectly. Cyrus and stratified are my go to guys when it comes to anything Mazdaspeed and I will recommend them to family, friends, strangers! Anyone. Keep up the good work and thank you Cyrus, you are awesome!

Purchased a 2007-2013 Mazdaspeed3 Custom Tune for my 2011 Mazdaspeed3. Goal: bolt on modifications/tuning with the stock engine and turbo. Tuned by Alejandro B.

Experience: very quick turnaround times with datalogs. Questions about the tune and modifications in general were answered fully. Even reviewed a datalog of a track lap, troubleshooting some issues noted on track day (outside the scope of the custom tune) - much appreciated! Alejandro is well versed on the Mazdaspeed platform, aware of the potential gains and issues with the COBB maps/software. Easy to chat with via e-mail.

Tune: Car started out with a flash tune for the modifications (pre-water methanol injection). Rough in lower gears, each progressive tune cleaned up the ride, increasing smoothness and power throughout the RPM range. 8 total iterations of the custom tune, including a tune with pops/crackles. Changed over from Load Based to Boost Based Tuning. Advanced timing to use the water methanol injection (Coolingmist).
Compared to the hub dynanometer, it was heartbreaking to see v1.1's v-dyno number. However, at the end of the tune, both HP and TQ had substantial gains (+68HP, +90TQ).

Excellent custom tuning experience with Alejandro @ Stratified. Very knowledgeable of the platform, and substantial gains to the smoothness and power of the Mazdaspeed3!! Highly recommended!

Recently got my mazdaspeed3 tuned by the great guys at stratified, and all i can say is wow. Stan, my tuner, addressed all my questions and concerns and put together a tune that is awesome, the car runs the best it ever has. Thanks Stan and to the great team at stratified

This was round 2 of my tunes with Stratified. I made some mods and moved to the East Coast and am on pump 93 octane v. Cali's 91. I not only got water I wanted. I got what my car wanted. I asked for power within reason. This is my DD and I couldn't risk zoom-zoom-boom. Each step of the way I was coached as to what was needed from me and what their target per iteration was. Through the process I learned about my car, the tuning process and reaffirmed my trust in the Stratified group. The last Dyno I ran before the final tune on a bolted car with stock K04 snail turned 256whp or approx 333hp at the crank. All completely use able power. I asked for a canyon carver and I got one. There are pleanty of straight line cars putting out higher hp and if I ever go that route, guess who my tuner will be. That's right, SA.

I did my research and choose who I felt was the most qualified, PROFESSIONAL tuners and I've been back twice and would recommend them for your car without a doubt. I really couldn't be happier with the tune. Thank you Stratified!
