    Just installed my Stratified tune and I’ve got to say — the process was super easy. Flashing it through my Cobb Accessport took no time at all, and the results were immediate. My Mk6 honestly feels like a different car now. What really stood out is that if you requested crackle tune, Stratified gives you two versions of the tune: one with crackle and one without. It’s perfect — I can enjoy a clean, daily-driveable setup, and then switch to the crackle tune for a cruise night or special occasion. My MK6 now has borderline personality disorder in ECU format.

    Highly recommend it if you’re looking to wake your GTI up the right way.

    Stratified is the ONLY way to go for the mk6 GTI. Clayton was a huge help with getting things sorted for the tune. This tune breaths new life into the car and I cannot wait to continue pushing it further.

    I am highly impressed with this Tune and the potential it has unlocked for the MK6 generation. I highly recommend this to anyone with the MK6 platform for its ease of installation & continual support. I have stuck with Stratified as I continue to modify my car and will continue to should I choose to upgrade more/upgrade to a newer platform. Huge shoutout to Clayton for the friendliness and support & and I will continue to suggest this Stratified Flash tune to new people on the MK6 platform.

    Super easy process and a HUGE step up from the OTS Cobb tunes that come preloaded on the accessport. If you're not getting a custom tune, there's not a better option than these flash tunes, hands down.

    I have a manual swapped 2011 gti and after I got the tune I was encountering rev limiter issues so I emailed back and they got it fixed right away for me. The tune runs great and the car feels way better than on any of the Cobb maps.
