'99 M6 with boltons... low #'s?
'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.

He has an LS6 intake. By the way, your numbers seem right on. Mine are in my sig. Almoast the same car.

Plus, should not the true duals make more, or is that just under the curve? (which would still stink for me 'cuz I seem to be down on the low end... arrr I want to post the graph)

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.
