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

I recently finished my 93 and E85 tune with Mike and all I can say is this by far the best purchase for my speed 3. The end result of my E85 tune was 309 WHP and 350 ftlbs of torque on a stock turbo and intercooler! Mike spent more time than he was required to for my tune to make sure we mad the most horsepower safely and reliably. I learned more about my car during the tuning process and was able to troubleshoot things a lot quicker. No matter what mods you have or if you don't have any this is the best bang for your buck mod. I mean on E85 I made 75 or 80 HP more than when I started. I will absolutely come back once I go big turbo and forged internals. Thanks again Mike!

Lex is everything I want in a tuner. I was so pleased with my 93 octane tune I immediately wanted an e85 tune for track days. Having an access port was one of the reasons I got my Speed 3 and have Lex as a tuner makes me again thankful I have a Speed. Car is so much more driveable in the powerband.
