    Had a fried ECU on my BK1 and was in need of a new one. They ended up supplying and throwing a tune on it. Got a great deal during their Black Friday sale. Installed their ECU and runs beautifully now. THANK YOU SO MUCH!

    Jay is an amazing guy who helped me build my motor. It was a long Process but he was patient to answer all of my question and at the end of the day we ended up making good horsepower Numbers

    The only person I trust with performance modifications on the genesis. I've been running his custom tune for over 6 years with zero issues. Great pricing for retunes when more modifications were made. The tune makes the car perform so much better and is much more enjoyable to drive. They're also able to order any parts you need and even do their own fabrication when needed (super clean custom work!). I've gotten work done elsewhere that needed to be corrected by Jay. His knowledge of the genesis is unmatched and I'll always take the 90 mile drive down when I need any work.

    Jay is the man. Drove 6 hours to have him tune my 2013 Genesis Coupe. He walked me through the process and kept me informed on the changes he was making after each pull. This guy knows his stuff! I was able to get an increase of about 60hp/30tq over his stage 1.5 canned tune that I had previously. He was also able to dial in the water methanol kit that I had installed as well. I'll be back when it's time for a bigger turbo!

    Went with a friend to have his Genesis tuned by Jay and we drove out from Detroit through the night 9 hours and he made sure to be there for us on the weekend to make the long trip worth it. Work was done quick and effectively. Tune was great car felt awesome. And felt that we also made a great friend that enjoys his work, has passion for what he does and cars in general definitely deserves some spotlight attention. Would recommend to more friends. Thanks !
