Is the difference in performance worth the money.I was gonna go with the LS6 manifold and portTB but have been hearing alot of good things about the Fast90/90 set-up.Will it go well with the K/N FIPK.The Fast90 setup is about $500 to 600 more than the LS6 portTB setup. I will be getting a dyno tune and maybe a 100-125 shot in the future so take that into consideration.

depends on more than what you have listed. on a stock ls1, the fast 90 will make more power than an ls6 manifold, but may not be worth the extra coin to you.

Right now I just have the Fipk AND Corsa Cat. Was planning on getting the PaceLTs and ory but I think Im gonna hold and do the LTs right before I get a tune done so I dont have to buy the simulators.

From what I have seen is that the LS1-LS6-FAST intake all flow about the same from below 5000RPM. From 5000RPM and up the LS6 makes more HP/TQ than the LS1 intake.The 90mm FAST makes more HP/TQ than the LS6 from 5000RPMs and up.The LS6 intake is a great upgrade over the LS1 for the money.Depends on what you use the car for if you got some better heads,a big cam,or drag race alot getting the FAST mite be worth it. You could get the LS6 and save the money also you can find a used one for cheap.
