Did a great job on my Corvette. Took great care of it, went the extra mile and reasonably priced. Highly recommend.

I had an ongoing problem getting an LS1 on my street rod to idle correctly and also throwing a CEL. I'm very grateful John took on the challenge, because now it runs perfect and I can finally enjoy it. John is honest and knows his tuning. I highly recommend.
