Dyno'd the 99 Corvette FRC today :) I decided to add the new Halltech Stinger Air Intake System and she put down 331.5rwhp/346.3rwtq on the second pull. The only other mod on the car is Borla Stingers. The #'s seem kind of high to me so I checked to see if I had an ls6 intake and the #'s I pulled off the intake were 12556333. I cant seem to find those #'s on GM parts anywhere.

Now that I think about it I can't recall ever seeing the standard EGR system like on the Fbody on the C5. Wonder what the difference is between your manifold and the LS6 if anything?????? Regardless, those are some awesome numbers!
