Vit has tuned my car from n/a s/c and turbo'd since 2012 my car has been my daily driver the whole time. I have a stock block and I rally the $#*! out of my car I'm making 450 hp I honestly thought I would of blown my motor a long time ago. Vit is very kind and generous he's invited me into his own home and his wife made me dinner. I noticed a few bad reviews on here. I didn't experience any rudeness from vit.
