Just finished up my 93 and E30 tune on my RS with Ke. It's been a great experience and can't suggest these guys enough. Alex tuned my speed3 a few years back so I knew I'd be coming back. My RS runs great and pulls super hard. About to go big turbo so I'll be back!

By far the best experience ive had w a tune/tuner. Definitely worth the money hands down. I have completely full bolts ons and started with 17 psi. I wound up ending with 25.75 psi. Very torquey and very quick. My tuner was very thorough. They made sure they could pull the absolute most of it and thats what you look for in a tuner/tune. The most bang for your buck and they did more then deliver. Im very very satisfied with them and would highly recommend them to anyone looking to further their power. Can't say enough good things about it, absolutely great.

Customer from germany here. Got my Big Turbo Focus ST Mk3.5 tuned by Ke Xu. Really love the tune and the way the car performs now. Ke Xu responded really fast everytime. I reached my power goals and got a reliable tune aswell. Would recommend this protune anytime.

I purchased a tune for my focus RS and Ke Xu was the technician that assisted me throughout the entire process. He was very helpful and prompt on any questions I had. My car feels totally different with the tune! Thank you Ke Xu!!

Hello, I have a 2018 focus st. I worked with Ke Xu, he did an awesome job. At first when I did the install and added the first map I was underwhelmed, I thought I made a big mistake. However after working with Ke, thirteen maps later he got it dialed in. The care runs AWESOME! I could not be happier with the results. I can't wait to get to the dyno and the track.
A BIG THANKS TO STRATIFIED TUNING AND KE !

Very experienced tuner!! Super happy!! I have been building cars all my life and can say these guys 100% know what they are doing!!
