I was waiting for somebody to point that out
There was a member here about 1 1/2 years ago that had a Fast 90 on a cam only car and lost hp & tq then he down graded to the Fast 78 and gained the power back..
A Fast 90 is only needed when you are using Cylinder heads that are capable of flowing over 280 cfm
The stock LS-1 241 casting heads on 2001-2002 Cars only flow 231 at .700 lift which won't even put most people close to even needing it..
Unless you are using a Huge *** cam..
