Default 90mm Throttle Body
I have done some research and found the I am needing an LS2 90mm throttle body for my FAST intake swap. Can it be from a Corvette or GTO?

I ran a factory 90mm TB with a pigtail adapter without a tune and the car ran fine.

I recommend the plug-n-play adapter harness from Racetronix, not Casper's. Better quality and actually is a few dollars less last time I checked.

If your MAP sensor gets relocated to the front you may need the extension for it too.
