First off as a Master Automotive Technician I have driven thousands of different cars with different aftermarket tunes over the last 20 years. I own a 2016 Fiesta ST with a muffler delete and a drop in air filter. I was previously running Cobb OTS 93 octane map. When I purchased the E30 tune from Stratified, I was blown away at how well the engine ran. It not only produces considerably more power with less knock and more ideal AFR's than the Cobb OTS 93 octane map when your under boost, part throttle and cruising are also much better. I require less throttle to accelerate for normal driving and have more torque when I'm cruising at low rpms in high gear further requiring lesser amounts of throttle to maintain speed. Stratified Automotive have some great engineers and deliver a quality product. I will definitely be working with them on other projects in the future.

I have tried a variety of tunes and the Stratified tune is the most impressive.

The exhaust sounds great, the power is smooth throughout the rev range and the car accelerates fantastically.
Thanks to Alex for all his work and great service.

Upgraded my ancient 2.10 ots to 3 (stage 3) and pretty big difference in power and response.
I have this saved as a 98 map in case i ever run out of E85 and have to switch over maps

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

After Christmas I had the opportunity to go Stage 3 on my 2014 Ford Focus ST and have received my final revision for my 91 and E30 custom tunes from Stratified. I could not be happier with the result. Cyrus worked his magic and tuned the car to my specifications of increasing power while maintaining the reliability of a daily driver. I am a member of the AZ ST Club out here and Arizona and was able to drive a Stage 3 ST with a Stratified Flash Tune prior to purchasing this one, however I had not driven one that was custom tuned. After driving both now, I would highly recommend spending the money on the Custom Tune. Cyrus noticed some abnormalities in my datalogs that were caused by poor fuel quality (Chevron 91 Octane, Common issue in AZ) which would not have been noticed with the flash tune. For those interested, my car, on the E30 tune, was putting out a healthy 290 HP and 360 lb/ft of torque to the front wheels. Overall, I do highly recommend the Custom Tune and look forward to coming to stratified for any future endeavors!

From my first map to my last, it's been a total pleasure working with Stratified!I've learned a lot in the process as well, and have felt my car go from something conservative to something that is now a blast to drive! Alex has made my tuning experience exactly what I've always wanted it to be, something fun, informative and best of all something that ends with amazing results!
