I do a lot of tuning on the V8 cars here, even tune on a twin turbo viper that comes out of a shop that is highly respected and A LOT of fast cars come out of in the American muscle crowd here.. especially the LS1 cars around here... maybe that helps some

I know 10+ years ago when i started running a lot around here they absolutely HATED my DSMs hahahaha.
