'99 M6 with boltons... low #'s?
I got two pulls at Speed Inc:
Pull 1:
HP: 342.5
TQ: 348.8
Pull 2:
HP: 342.4
TQ: 351.8
I will try to get my graph scanned and posted. There is a wierd dip in power from 5600 RPM through 6000 RPM. I would like an opinion on what that could be as soon as I get the graph up. I sure hope that nothing is wrong.
Mods are in my sig. So what do you all think? It's still on the stock tune. The numbers seem a bit low to me, since my friend's 2002 z28 got 340.9 HP and 352.7 TQ on the same dyno on a differant day and he's still running cats! Also, he has more power under the curve, too, which confuses me since I have true duals and he has a GMMG.
...Maybe I'm just freaking over nothing. I am untuned after all.
Oh, BTW, my Air Fuel ratio was 12.9 across the board, so I think that's okay, right?

The next part I get! Cam or heads and cam are for sure in my future!

Numbers seem good to me, but then again I only have 300 RWHP . Seriously though, that's still good, over 400HP at the engine and every car is different. Like how my car consumes no oil... but Joe Blow down the street might drink 1 quart every 3000 miles.
Dyno day is Saturday... I'll be happy if I gain 1 HP with my new tune, and removel of that retarded IAT temp tricker. I can't believe I found that on my car

Remember, your friends 02 has the LS6 intake. I know it does not account for a huge amount of power but those 01-02 LS1s seem to really put down more power mod for mod than the 97-00s.

My point? I should be making a lot more than you, but I'm not. I dunno, maybe it's just that I need tuning...

I think your number's are right on, especially being untuned. I have very similar setup as you except I don't have true dual's, but I also don't have muffler's either. I figured I'd be in the 340-350rwhp range once I get it dyno tuned. Before the LT's, ory and LS6 intake I dynoe'd 315rwhp and 326rwtq.
