Well for starters, my friends on their ZL1's the first thing they did was a CAI, LT headers, exhaust and a pulley swap and a new tune after that. That alone netted them some nice gains. But the ZL1 stock is a pretty sweet thrill. After they did all that, one of them did the flex fuel sensor, injector upgrade for e85, fuel system upgrade and a new tune, and he ended up at around 660 rwhp... But it is all up to as how much you want to spend, and how far you want to go. Doesn't take much with stock setup to get in more trouble.. lol
