ok ive got a 07' (NNBS) 2WD with the 4.8 and I dont know where i should go next?? alright so here goes the list of mods thus far:
-K&N CAI
-vinci "trucker" cam and springs
-black bear tune
-long tubes, bullet cats, into true duals
-3200 stall converter
-4.10 gears w/ locker

next im thinking rockers, lifters and pushrods. along with that the LSXRT manifold or something of that nature. not really looking to do forced induction at this point. At most nitrous... any input you guys have would be awesome!! thanks!

 

I would do nitrous over that expensive Intake. 150 shot or so would wake it up. A good plate kit and if it hooks, it will fly.

 

yeah I mean its not so much an either/or I could do the nitrous and the intake. Ive just heard that these intake arent exactly to best flowing so, just trying to get a little more air flow.

 

I've heard some drivability issues with those intakes
and to add...at that price its just not worth the gains, I haven't found any used and new its what...$1050?
for about $800'ish you can get a decent nitrous kit with adjustable jets
and $800 for 150-250hp is definitely dollar/pony worth it
