Disappointing LE2 Dyno #s

Hi,
I finally got to dyno my car a year after I built it up. I dyno'd it at Alternative motorsports in OKC. Here are the numbers: SAE peak 352.7 HP 339.9 TQ. If anyone can tell me why the numbers are so low (I believe I'm supposed to have atleast 400-420RWHP) please let me know. My mods are in my sig. Everything on the dyno looks good except the numbers. Car ran/runs strong. Great torque curve but low numbers. Air/fuel ratio looks about right. Anyone with any ideas please let me know. Thanks for all your help.

Um I want to know why the a/f is off so much from back to back pulls. I realize you let the car cool down in between runs but damn.

All I have to say is, did you degree the cam when you were installing it? Or whom ever installed it? Guess how I know?

Did you do a scan?

Do you have knock or any other anomolous readings?

I second why is your a/f so different on back to back pulls and whoever installed the cam could have not degreed it correctly.
