Did a 91 and e85 tune with Alex. He is a true professional. The results from both tunes far surpass my meager attempts at self tuning. Unless you are willing to devote days to mastering the DISI platform, it is a solid investment to have Stratified tune your car instead. Power delivery is fantastic and overall drivability is great. I could not be more pleased.

I can't be happier with the custom 91/E85 tune from Alex. It feels like a completely different car now, so much more alive and responsive. You can bet that I'll return when I go to a bigger turbo. Thanks again Alex.

IMPRESSED! That is the single word that comes to mind when I think about the result of my Stratified Tune, not only is the power abundant but once it comes on it stays on till redline and never sounds off, AMAZING! Alex did a great job and I will be coming back for an e85 tune in the spring and again in the near future for a bnrS3 tune. 5 Stars all the way, go with Stratified and you will not be disappointed, money very well spent.

Best money spent so far. Alex was a huge help and really knows what he is doing. We went through 10 different maps to get it so it's right where it should be. Even with the bad California gas I have to deal with the tune came out great. Feels faster and smoother in the power delivery. I also bought the Guardian angel for peace of mind and it was simple to install and also works great. I would recommend this company as a whole to anyone who wants quality parts and friendly and knowledgeable staff.
Thank you again.

I recently finished my E -tune with Mike and I couldn't be happier with the car. All my revisions and emails were answered within 48 hours and Mike gladly took more time than he was required just to make the tune perfect. Mike was very patient and courteous during the tune and got my speed 3 to over 300hp on bolts only! Hands down best modification for the car at an unbeatable price. The feeling of making more horsepower and doing it safely makes this the best mod no matter if your stock or fully built. I will absolutely come back to stratified in the future as my build progresses.

This tune is very good, got the results I wanted and I have no complaints
