I would like to thank Stratified for an amazing tuning experience. They really know their stuff! I work two jobs and have a busy schedule but they were very patient with me during the tuning experience. Cyrus has my car running amazing and the difference is night and day. Especially the E30 tune! Turned my Fiesta ST into a little rocket! Again, thank you Stratified for your excellent work and continued support. Keep making things go faster!!!!

All I can is WOW, what an amazing experience tuning with Alex again! I had a Focus ST and went with a Stratified flash tune, it was a great initial learning process about my car and I loved the way it felt and drove. I have since traded in the ST for a Focus RS and I wanted a little bit more this time so I contacted Alex about doing a custom tune on the RS. I couldn't believe the difference it makes with a custom tune, the time and effort Alex puts into these tunes for our cars is amazing. You don't want to rush the process also as he takes his time and he may have you submit a few extra logs to ensure it's perfect. I also threw him a curve ball and asked to redo the pops and burbles mid way through tuning our second fuel and he didn't even blink, I received the updated tune and the pops were perfect. (He also went back and updated/resent my first fuel tune with the new pops before I asked.)

I would HIGHLY recommend Alex and Stratified Tuning to anyone wanting to get the most out of their ST/RS along with a great tuning experience. My car still has all of it's DD functionality, but a lot more bite now and it's exactly what an RS should be...V8's beware!

I came from the Cobb ots stage 2 tune. This stratified tune blows that one away. Much quicker throttle response, smoother and more powerful. The exhaust crackles is a cool touch for a change of pace sometimes. Thanks alot! I'll definitely be coming to Stratified for any future tuning as well.

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!

Very good way to further customize your car to fit your needs. The pops and bangs option is amazing and makes me feel like I'm driving a rally car. Only problem I found was that sometimes it took awhile to get a revision emailed back because of the amount of traffic Stratified gained. Still completely worth it and I am well satisfied.

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!
