I figured I would wait awhile before giving a review. My 2015 FoST has been Flash Tuned by Stratified since it had 500 miles on it and Stage 3. I have had zero problems with my tune and the car. Stratified's customer service is top notch via email or phone. I have since done many updates as they have been released and refined to ensure the Tune is running properly. Still trucking away at 21k miles. Thanks again Stratified.

I used the custom tune facility for my Focus RS and what a difference it has made to the car. It was previously M380 but Alex`s tune has taken it to the next level. Not only has he transformed my car but the contact and feedback was spot on. Emails replied to in a timely fashion and nothing was too much trouble as the tune was developed over time. I can highly recommend Stratified and I would definitely use them again despite being on the otherside of the planet !! Superb

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!
