Before the install I had a cam only 99 ss ran perfect. I decided to put heads, fast 90/ and a 90mm TB with 42lbs Injectors on at the same time. Now, i have hp tuners and have a tune that i thought would have been close to the setup i have. I uploaded it. and tryed to start the car, It started and idled for about 1-2 secs at 2500rpm then imeadiatly spiked to about 5500 and i shut it off. I also have had it just shut off on me right after it started ran for about 2 secs. Im not sure if this is mechanical or the tune, I tried my old tune to see if it would run and it does the same thing. Any ideas???

Check over all your work once again, vaccum lines, etc... But I think it might be a tune issue or one hell of a vaccum leak?

I did, Just pulled the intake off there is a crack on the bottom of the FAST 90mm intake, Almost sure thats the problem, im going to put my ls6 intake back on to rectify this problem/ Then fix the crack.

Well sir, you just cracked your intake because you didn't use the bolts that FAST includes with their intakes. The stock valley cover intakes are too tall. FAST intakes come with an flatter allen key bolt that sits low enough to clear the intake.

Hopefully you can try to epoxy it.
