Doug, I'm not sure if your buddy wants to come up to the Northbay but if he doesn't mind the travel I would suggest Lawrence. He races that 9 or 10 sec Lexus out at the track. If you get a hold of Vince, he will have all the info you need to get a hold of Lawrence (I forget what his shop is called). He is the go-to guy for Chevy tuning around these parts.
