It looks like the Ls2 throttle body outperformed thiers on the Fast 90 intake. lol 
All Intakes Tested
All Intakes Tested Probably a respost but here is a test performed by TPIS on each intake system combo available for the Ls1/2/6....I found it interesting.

Why is it that every test on the LS1, LS6, Weiand and F.A.S.T. manifolds peaked at 6800 or 7000 rpm. Only the LS2 manifold forced the peak at 6400. Everything I've read about cam selection says that the LS6 and F.A.S.T. are tuned to peak at 6300, and that camming for power above that point is only fighting the intake.
Any thoughts?

what about the TPIS spyder intake...i have speed density... are they saying that it is worth 40 hp over an ls6/75mm setup...
it lost at most 5-7 torque in the lower rpm ranges..negligible if you ask me.
