Good solid numbers. Start saving for a Maggie

Good numbers. Looks very similar

I've got an 07 that has damn near the same mods. The only difference is that I'm running Corsa instead of Magnaflow. With a tune by Ed Hutchings, (who is somewhat local to you) I turned out 385 hp/377 ft lbs.

His name on here is edcmat-l1 if you want to get it tuned.

But whatever you do, don't take it to VA Speed.

I think I'm set for now. I'm still trying to sell the car, so I won't be saving for a supercharger any time soon lol

And wow...I hear so many mixed stories about VA speed...whats the deal?

I had the exact same mods except im just running a muffler delete and made 365 as well. Didnt you make almost those numbers prior to the headers though?

it actually made 375!! I was real skeptical of those numbers. It read 10% high on my buddies car on the same night, and he didnt change his car between sessions.

I feel 365 is accurate

I made 373 rwhp on my dyno with almost the same mods (2005 CTS-V). Kooks, Cats, Corsa cat-back and ummm home made intake.

I had an 2007 CTS-V that had an intake and we ported the intake manifold and throttle body that made 372/383... no headers. Lucky LS2s...

i was thinking 380 was the norm for that setup.. still havent got mine tuned lol been like 6 months since i put the headers on

The good thing about LS motors is that with GM's standards, these things are typically +/-1% of each other with the same mods.
