Any Thought's?
 

I have a 2004 GTO w/ a 6sp, the mods are SLP long tubes, high flow cats, x-pipe, full 2.5 custom exhaust w/ super 40's, cold air intake, SLP underdrive, LS6 heads with all comp stuff, comp cam .588/.595 228/232@112+2. The car put down 336rwhp & 342tq before heads and cam, just wondering where i am at with this combo. The is not tuned yet but it will be very soon, i have not been driving it because thing's have been too busy. Let me know what you all think?

You should be close to 400 RWHP when tuned. I can't believe you are able to drive it untuned. There's a lot of stuff that the stock tune can't really accommodate there.

It drives but i did adjust the idle screw to get it to stay running. It seems the more that i've driven it the better it idle's. Iv'e only put about 100 miles on it since the swap and the drive home was really bad, wanted to die all the time coming to a stop. The ilde is about 900-950 right now, i hope it will idle around 800ish so you really hear the cam. It does sound good, I love it.
