I've got a race this friday against a Z06, and just went out after school to test my car a bit. I always just left the wastegate rod at stock length, so it always ran at 14 psi. I just turned in the actuator one full turn, tested it, and boost did not change. I thought that was wierd, so i turned it in another full turn, and boost still stayed the same! Now i'm confused. I just installed a new ign module and adjusted the cam sensore correctly on sunday and the missing problem i'd been having is gone, but in it's place is another problem. The motor makes a wierd raspy sounding rev/ vibration? at high rpms only under boost. It is not knocking, as my caspers guage told me it wasn't. Any body have any ideas as to what it could be? TIA, Lee
