Massive difference compared to Cobb's OTS maps, amazing throttle response! I worked with Alex twice in getting my MK7 GTI (stock IS20 turbo) tuned, first was w/ the stock clutch and the top-up with an aftermarket SMFW clutch.

Highly recommend Stratified and will likely re-tune with them if I ever upgrade to a bigger turbo. Haven't had the car dyno'd yet but will definitely update this review once I do.

Just wanted to give some positive feedback on my Stratified tune by Alex. Great experience and the car feels amazing, night and day difference from the COBB tunes. Keep up the great work!

I love my custom tune on my Mustang! If you have a Ecoboost Mustang, you need a tune. Alex knows what he is doing and is very diligent in getting the most out of the car but at the same time being safe. He ask what you want to do with your Mustang and listens to feedback and adjust accordingly. I can not imagine driving the car stock. Plus on a side note the Pops and Crackles are perfect, not to much and sound very organic!

Extremely happy with the tune. Reliable, responsive and with great power numbers, 30k miles on a x47r and a custom tune NO PROBLEMS. Will be coming back when I Aux Fuel.

Wow. Just wow.
I have a mk6 Gti and the first purchase I made was an accessport from Cobb. From there I've played with a couple different configurations ranging from stage 1+ with an APR full intake to Stage 2 high boost with the Cobb intake and 3in catless dp.

Stage 1 ots was great, Stage 2 was incredible, but words cannot describe how much better the stratified tune feels than anything I've felt. It's just perfect.

If you are reading this and want to get the tune, do it. I've fallen in love with my car all over again. Money well spent without a doubt.

Alejandro was awesome! He pretty much always replied within 24-48 hour with answers back to me. He did a great job tuning my GenWon MS3. Made huge power gains Compared to the OTS tunes. He worked with me for a couple months until everything was perfectly dialed in. I would recommend him 100%.
