dyno numbers?
just recently purchased a 2007 ls2 and attained the mod list from the previous owner and was just wondering what i should be looking to expect with a good tune car seems to be running a bit rich now w slight hesitation off the throttle at low rpm
mods are fully ported heads,bullet racing cams with 632 lift a 252 264 duration ,comp push rods , patriot retainers
comp cam gold rocker arms , titanium valve springs and retainers
kook longtube headers,slp loudmouth exhaust,custom x pipe, haltech intake

Need more info... Stock ported heads or aftermarket? That cam is HUGE for an LS2, probably has one hell of a time idling. What is the LSA? As an example, here is what I have:
LG 1-3/4" street series headers, no cats
230/234 114+2 cam (.598/.612 lift)
CNC'd stock heads
FAST 102
ported TB
WCC hurricane CAI
Stock bottom end
Borla Touring axleback
My car idles at 900 RPM with minimal lope. Made 468/445 on a Mustang dyno (485/440 on a Dynojet) at 24 degrees of timing and 12.7 AFR.
If you have stock displacement I would say that cam is way oversized for your application. It's probably worht doing more research to verify the cam specs.
