Just got back from the dyno w/ bolt-ons.
I really wanted a dyno run with just the lid and magnaflow catback which is what the car had when I bought it. But I got royally trashed by a c5 z06 and the speed bug got me.

Just wait, before you know you'll want a cam, then heads, and nitrous.

Very good numbers for still having a ls1 intake.

My 2000 had 241's on it as well.
GTO Crusin the 808 was a stock 2005 LS2 GTO with chip, k&n FIPK, and cat back exhaust.
He got 344rwhp.

oh, and...nice dyno numbers.
i apologize if you take offense to this, but...dynos are tuning tools, each one reads differently. go ahead and run a 12.2, apparently you have the power, as the timeslip is what tells the story.
continue dyno worship..

Anway, I have to agree with you on the dyno numbers. Mine made a lowly 371rwhp with full boltons and a 232/234 cam through a 12-bolt, but it runs 12.0 (6-speed and crappy launch) and pulls ***** from a roll.
It looks like your numbers are closer to 351rwhp not 365rwhp.
Also the graph needs to be smoother, not set at 0.
I setup the dyno day with the local shop and have Justin's WinPep files as well as the jpeg that Justin originally posted. Smoothing to 5 brings the hp down to 351. Very strong for an untuned 2000!

A dyno will be my only real way of telling any progress with mods. Besides adding the numbers of cars that I put on 05 Mustang GTs now.
