Stock LS4 Dyno Test?

Does anyone have a dyno test for the LS4. I know GM's dyno said it was 303 HP and 323 ft-lbs. But GM also has a tendency to underrate their V8's.

If anyone has different results than what GM posted, lets hear it.

That's Chp...Whp is commonly between 242-254hp for stock LS4 vehicles. No one is doing an engine dyno to compare those numbers GM provided.

Once I get my tune from Vector motorsports, I will show you guys the before and after. I am hoping for some better gains with some of the changes Chris will be doing for me.
