Default Bolt-ON GTO dyno

This is its first time being tuned, and its second time on a Dyno. Pre-LTs I was sitting at 354/349. I was very happy with the outcome, for my very minimal mods. My final numbers were 383/411

mods: pacesetter LTs, KN CAI, cat-less, x-pipe,
the first one is corrected, followed by the uncorrected graph.
This was on a Dynocom.

Was the baseline done on the same dyno? A 30 rwhp gain from LT's and a tune is very nice

What's the difference between the two graphs? Top one is SAE i presume.

Why such a conservative tune? Looks pretty rich.

Yes, the top one is corrected. They was issues with the car and it started to knock. However, the RWHP is about even with other tuned LTs/bolt-on LS2s that they have.

The baseline was done on a dynojet, but the tune who did the baseline moved out of the state.

comparing gains from one dyno to another is akin to comparing, well, 2 different things that are alike but end up telling you nothing in the end.

Its kinda of hard for me to get from here FL to Indiana to see what gains i would get on the same dyno. I have traped at most 3mph more then i ever did pre headers(without tune) and am running a 4mph consistintly faster then pre headers

avg trap pre headers 107 most 109.89
avg trap post headers 111 most 112.55
I also gained about .5 in pb
pre headers 13.102
post headers 12.623

Yeah, I figured the baseline was on a different dyno than the current.

Nice numers. Mine was 395/415 on SNL's dyno with (almost) all of the bolt-ons. Traped 113. At that time I didn't have an EWP, RR's, or a UDP. With my new UDP, it would have been over 400, but we added a cam at the same time.

LS2's FTW!

There's that crazy torque again...

FWIW, my GTO with the same mods I/H/E and tune(catted vs your catless) put down 381/386 and was also trapping 112-113.
