I completed (or so I thought) all the modifications on my 09 speed3 and decided to get a tune. Not sure who to go with I searched around on the forums and everyone seemed happy with stratified so that is who I went with. Very happy with the tune I received. Lex, was extremely patient and listened to how I wanted the car to handle and drive. I am now further addicted and have decided to order up a stage two water meth kit and will be contacting Lex again to retune the car. Two thumbs up great customer service and quick to get back with new revisions for the car!

Went with the e85 tune and I love it. Ended up going on a road trip after I got the tune and had to switch to an OTS 91 map because of the lack of 93 and e85 where I went and it was a HUGE change in power. Once I got back home and filled up with the 93/e85 mix I just wanted to floor it every chance I got.
Lex is great and makes sure you get both power and reliability out of the tune. Highly recommended.

My tune period with Stratified has worked very well.
Throughout the tune service has been really good. Have assisted me at the slightest problem.
Also very satisfied with the final product of the tune, car runs really well!

Alex is one of the best of the best. Customer service is top notch. He explained with details every map sent to me. Can't say enough about him and I will come back for more tuning with future big turbo set up.

The Stratified tune is the best money I have spent on my car. Not only did Alex deliver exactly what I wanted, he worked with me through issues that popped up completely unrelated to the tuning process. Excellent customer service in addition to technical expertise. I'm thrilled with the results

The vehicle is a total night and day difference. Well worth the money I spent to get this done. I plan on getting a top up tune in the future once I get my internals installed!
