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.

So far I am very happy with the tune I received from Stratified. The power gains are very noticeable throughout the rev range and the rev hang I used to experience with the Cobb OTS tunes are gone! Within 2 hours of purchasing my tune from Stratified's website I received a tune via email. Extremely fast turnaround and Aaron answered all my emails/questions very promptly. I would definitely recommended Stratified to other ST owners.
