Default FAST 90/90 On Cam Only Car?

Has anyone run the FAST 90/90 setup on a cam only car on a LS1? Im thinking of add this to my GTO. Right now I have pretty much all the bolt ons:

K&N Intake
Kooks 1.75 Lt's w/cats
Borla Cat-Back
220/224 .597/.589 @ 113 LSA


Any thoughts about how effective this setup might be? I might spring for P/P heads in the future but for now the FAST setup is in my price range. I'll probably need bigger injectors also right? My injectors are at 95% right now, pretty much maxed out.

TSP said the factory injectors 01 up are good for 475 rwh.

While they might feed enough fuel, I wouldn't trust them past a cam-only setup, if even with that. My stock injectors are at 83% with only bolt-ons...

It is beneficial if you have the money to do it. Think about it this way. You are not going to overflow the LSX engines with a 90/90 setup.

I just installed a Fast 90/90 setup on my cam only car, and I definitely consider it money well spent. Throttle response improved greatly, and while I haven't gotten it to the dyno yet it feels like it's picked up power everywhere, from off-idle to redline, enough so that the butt dyno definitely feels the difference. Not only that, but it's also a solid foundation for any future mods you make.

My shop is a 75.00 hr labor rate and I could see this as a shop rate of around 2.5 hrs. If you dont have a NOS setup that could generate some extra time to R & R. SO a guesstimate of around 190.00 bucks.

That is very realistic, just trying to give a ballpark on what mosts shops would charge.

you already have the ls6 intake.. instead of spending 1200 on manifold and tb, have your heads ported or get some new ones
