Kinda pisssed... Well I dont know where you guys are getting these HP numbers....but I am pulling 385rwhp with PP 5.3 heads, LT headers, 224/224 .581 114, LS1 edit tune. Unless I'm doing something majorly wrong, I'm dissapointed. I know my dyno was calibrated correctly in terms of Atomspheric pressure and tempeture....The parts have installed correctly.....is EVERYBODY seeing over 400 with these type of parts?? I'm not bashing, I want to know what going on.....

What was your A/F if it was dyno tuned? Also who tuned it?
I would take it to the track and see how it performs before I got too discouraged. Yeah, it would be nice to brag about high numbers, but that doesnt tell the whole story...

Any knock retard, low timing, etc?? Sounds a little low, i am taking it you have a M6 car not an A4? Get it out to the track and see like Sean said. Does the car seem sluggish, slow, etc?? Can you post the graph?

HA thanks. I dont think it was Augostino though. They only saw it after the work was done.

Can you post up a dyno graph for us to look at? Did you autotap the run? It does appear low for a H/C package, but I would not go off of dyno #'s I'd take it to the track. In regards to HP, I have a cam only 216/220 cam and it put down 382RWHP through my old 10-bolt setup.

What JRP said... gains are relative. If your car dynoed on the low end to begin with when it was stock or relatively stock, then I wouldn't expect too big of gains. Plus if the dyno you're on tends to run on the low end, then your numbers might seem a little low too.
I only dynoed 336rwhp with the mods in my sig, which I've seen cars with similar mods to mine dynoing 20 hp higher than that... but my car runs strong at the track, so I really don't care if it ain't a dyno queen.
Always keep in mind that the dyno is a tool to get your setup right... the real test is how the car actually performs.

I agree with everything said, especially jrp and Tranzor, but one last thing to remember, is every engine is different. Some people get better than average numbers, but in order for it to be an average, someone needs to get less than average numbers. It sucks if youre one of the latter, but it happens and doesn't necessarily mean anything is wrong with your car or the tune. But as already said, get some track numbers.

Do you mean Agostino in Ontario? Their dyno traditionally reads low in comparision to some others I have been on.
I still think your numbers should be a little higher though.
What were your baseline numbers and what does the car run now?

My buddy's car dynos 402 RWHP locally. He traps 123-124 in the quarter, full weight (3550+)
My car dynos over 450 (on a different dyno). I trap 124-126 on the same day at the same track, <3400 lbs.
Makes you go hmm...
Dynos are tuning tools. Don't get caught up in numbers.
Especially the ones posted on the internet. Take it to the track and see how it MPH's. Then start comparing.

Well, the car started out stock at 315rwhp.
I dont have a graph to post, I dont have a host.
I am running Cats with true dual 2.5".
The firehawk has the 2002 SLP lid.
No underdrive pulleys or ported TB's or thermostates.
Yes Agostino in Toronto
I will be getting to the track in the upcoming week so I am looking forward to that. It is somewhat dissapointing in terms of numbers....however it does feel 10 times stronger than it used to. So I am pleased with that. We'll see. Thanks for the opinions.

Cats are anywhere from 18-24RWHP depending on what cat you are running. 160 stat and fan programming should definitely be done as well as bumping up the timing. (cooler stat and fans allow a couple degrees more timing without KR.
I think with the other boltons and no cats you would make ~420RWHP with further tuning...
