Was very pleased with how this tune came out sounds amazing and performs very well. I had forgotten to mention one of the modifications done to my car so I shot them an email and they responded within five minutes. Great customer service.

Incredible. Been running them for about 20k miles now, not a single complaint not a single problem just me and my GTI gapping 90 percent of cars on the street

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
