Tell me what you'd guess my rwhp/tq gains would be IF I were to add a FAST LSX Intake and a 90mm TB over my current LS6 Intake and Ported (stock) TB.

I'll be doing my H/C install soon (heads and cam listed below, stock bore), and am debating on whether or not to also do the intake & TB, since they'll be off for the H/C install anyways.

Current:
Stock LS6 Intake
Stock-Ported TB (w/ epoxied wedge)
Stage-II Ported 243 Heads (flows 292 @ .500, 319 @ .600)
Comp XE-R 224/224 .581" 114 LSA
85mm MAF (to be installed with H/C and accompanying tune)
StainlessWorks Longtubes
...and all the various other misc bolt-ons (ie, lid, ASP UD pulley, etc)....

How much more hp/tq would I see over the LS6 intake and my stock-ported TB?

Seeing some educated guesses will help me decide if its worth it or not.

i'd say 10 -15 rw,thats all i'm expecting out of mine.i got the 90/90 because later on i will probably get a 402/408.

Last weekend I tuned a buddy's 02 Z06. He has LG headers, zip tie mod and added Fast 90 w/ a ls2 TB. He picked up 15/13 and didn't lose a single hp at any rpm.
