LS2 headers vs intake manifold
I have a 2005 with a CAI and x pipe. My budget allows for one modification only at this time. Anyone know if an intake manifold (ie Fast 92 or 102) or headers would yield more hp gains?
Thanks

I'd vote for the headers.
For the weight loss and sound improvement.
My reading recalls that intakes don't add that much power if the engine has a stock cam.
I think the headers will conservatively add 10 HP, the intake 1 or 2 HP.
Repeating I would add the headers and next add hi flow cats before an intake.
Once all done, then get a tune and I'd wager with the above mods and a tune you maybe looking at a 30 HP gain.
Good luck.

The LS2 benefits well from an intake upgrade. The LS3 does not.
OP could do the intake and not worry about tuning. Headers will require a tune.
EDIT: Long tube headers that is. Shorty's don't need a tune.

Diablo is the best of those style tuning devices -- Far superior then any handheld type-Depends on the mods on your car and if you run one of their canned tunes or have them specifically tune your car
For most applications Diablo is great
However if you want to go all out and are running a big cam and other major mods you best bet would be a custom tune with HP or EFILIVE-------
I prefer a "street driven" tune as compared to a dyno tune---With a dyno tune they do not drive the car for street ability ---idle quality or start up Just for WOT HP/TQ from about 4000-6500 RPM's-- No launch tuning----No trans tuning if it's an auto trans like shift firmness--shift point correction---TCC lock/unlock
