Excellent! The power differential of the 04's advertised 316 bhp to the dyno'ed 172rwhp tells me a differential of 45%

or someone at GM was lying.Normal loss' run 15-20 percent on a regular rwd car with a standard. Auto's roll 20 to 22% loss.
With an advertised 325bhp, my '05 should dyno at 178rwhp. Add in a 135-150 rwhp gain and make it a mid-15 second runner.
BTW, I think that the stated 172rwhp numbers are way low. I think 30% loss is more accurate, or 228rwhp'ish. This is a semi-educated opinion, so don't go betting on it. I'm excited and I now know a blower is in my future.
Also, the 04L is two months old,and has no mods yet, thanx to my brother ditching it and causing 15K in damage. A ported blower,exhaust and tune is on the plate.
Thanx Ken....I appreciate all your input...
