My car is already dynotuned and chipped with a diablosport chip...the tunner set the idle at 900RPM's but I would like to have it a little lower to hear the cam some more...what is a good idle speed? also can the TSP voltage be changed without affecting the tune???

There are a few different ways of setting up the idle in a tune. I'd get ahold of your tuner and ask his opinion or just try it and remember how to get back to where you were after the change.

Pull the negative battery cable and hold the brake a few seconds to clear the ISC learning.
