I second what John said in the first review! Clayton has been excellent through the entire tuning process! My WRX runs so much better and is much more fun to drive now! I highly recommend Stratified for all your tuning needs!

Gotta love Stratified great customer service & great quality tunes. Stage 1 low torque may be rather conservative but extremely safe compared to other stage 1 tunes. High torque past stage 1 or even their custom tune is where stratified truly shines!

Stratified is, in my opinion, the best custom tuner for the MK6 GTI. Clayton was patient and helped me with issues after installing the Aux Fuel Kit and LPFP took the extra time to explain things and offer feedback.

If your running (or plan to run) a K04 or aftermarket turbo
If you have a MK6 GTI running larger than stock turbo and have access to E85, just with their Pro-Tune. The car feels almost stock in terms of drivability and delivers smooth, linear power. It took a few revisions to finalize the tune Their Pro-Tune on Ethanol Blend completelh changed how the car feels. Ethanol really wakes up the 2.0 and now almost feels naturally aspirated.

Stratified still supports the MK6 when most tuners moved on. Their Pro-Tune is a great option for anyone looking to dial the car in.

John has been great and Worked my tune up to be pretty strong Car Would Def Recommend Stratified to many

After coming from another very well known Cobb tuner in the MK7 world that was way too aggressive for my likings I tried stratified.
This is the DSG tune you're looking for! Parking lot and around town driving is programmed as it should be. No more jerky starts and stops or gear searching. Holds the power as it should and holds the RPMs to perfectly match their tune. You will not be disappointed!

After being unhappy with a another very well-known Cobb tuner In the MK7 world I decided to give stratified a try. So glad I did! Around town driving which is 95% of real world driving is so much smoother and controlled. No more jerky starts or blowing the tires off way too early. The stratified tune is smooth controllable and with power distributed the way it should be. Highly recommended! The stratified team has been great with any questions or concerns I had.
