02 ZO6 LS1 vs Fbody LS1, Whats Different? Ok, heres the deal. My boss has a 02 ZO6 Vette rated at 405 hp. I have a 02 Firehawk rated at 345 hp. We both got the same motor, LS6 intake, Cam, lifters etc...etc.... Where the heck did that extra 60hp come from? Is it the PCM, Heads, Exhaust? Just wanna know cause maybe I could apply some of those upgrades to break the 400hp mark.

A z06 has an LS6, not an LS1. You have the same intake and probably block, but he has better heads/cam/springs.
The Corvettes also make more power from their exhaust setup, because the F-Body design/routing is poor and inefficient.

stock Vettes came with a LS1.

He has heads and cam over you, a bigger MAF, and a lighter car.

A cam in the mid 22x's to 230 duration should net you around 390 at the wheels with full bolt-ons. You could get a bigger cam like the ms3 or ms4 and then push more to the wheels than him.

Thanks for the numbers on the cam. It will def make my choice alot easier. I just want my Hawk to be faster than his Vette. Of course his hp numbers are at the flywheel not the wheels so I think I could overpower him with the correct Head/Cam package.

Most stock Z06s seem to trap 115-118, with a few exceptions. A full weight F-body is probably going to need 400 to the wheels to make a race out of it. Since you're an A4, you'll have an advantage from a dig, but you'll have your work cut out for you from a roll. A decent sized cam and appropriately matched converter should put him in your rear view from any speed.
