if you have the stock tb, or aftermarket with the right thrttle cam and your blade isn't opening all the way, and is still not against the throttle stop, check your cable and adjust it (04 GTO) has yhe cable length adjustment right on top of the intake.....not sure if your F-bodies are in the exact same place
