I just did this, and heard the clicking noises. Don't know if this really made any "seat of the pants" noticeable differences. Can't hurt...right? I'll do this before I autoX from now on... Any statement about this in the repair manual???
I'm asking some corvette engineers that I know if "they" would do something like: reduced HP during break in period < 3k miles and the throttle reset...
