the guys there tried telling me that those numbers were right which is not correct. Installing a cam friday and going to take it back over there and a buddy of mine is going to tune it so I'm hoping its picks ALOT up. I'll post results

The car runs really strong. I've run 2 other cars w/ similar mods and put a little over a car length on both of them. So i know its not the car, wondering if a tune and letting it cool down next time is going to really pick it up.

no, dynojet. But, a z06 dyno'd their today w/ longtubes, exhaust, predator tuner and cold air put down 369. I think its an 02, I know its the 405hp Z06. Seems low like my car as well as several others that have dyno'd there.

do you have the graph with the airfuel reading ? Did you just want to know your power or was this car tuned ? Seems kinda pathetic to tell you the truth with the ls6 intake factory on your car .

Agreed, numbers seem way low. I have basically the same mods you do with a ported T/B and made numbers in sig through a 9" rear and steal driveshaft (known to suck up some HP). In fact, I made over 300 bone stock, and almost 320 with just a lid, filter, MAF, and some free mods, and mine is an early 2000 with the older supposedly less capable heads. I would either look seriously at your tune or something. As far as using the Vettes numbers to compare with, don't. It is a known fact that GM under rated the HP in the F-body. A 305 HP f-body will almost always dyno the same if not better than a 350 HP rated vette. The Vette also has slightly higher parasitic losses than a F-body so in theory the same motor in a Vette would dyno slightly less.
270rwhp since im still running a 2000 ls1 intake 
If its untuned that is your biggest problem! Mine was only putting down like 320 h.p. And 340ish tq before my tune i picked 15 h.p.+ and 30 t.q. . Check around your area for someone cheaper to tune it. I got a full tune for $200 Your car will feel a lot better.
