I thought with the predator you can back out some of the timing on an as-needed basis. Also, I remember reading another thread many months ago from a tuner suggesting that the timing curves for the C6 were pretty damn good and there was nothing to be gained from significantly changing them.

Is it only at low RPM? I find that you can't advance the timing at all (above stock) below 2000 RPM or you'll end up with knock/retard. The mid and upper RPM range, however, can take quite a bit of additional advance without pinging. Personally, I started with the stock tune and added a little timing to the mid/high RPM range myself. If you want to stick with the Diablo tune, try setting the lowest RPM timing back about -6% and see if that solves it.

The car does not ping until about half to three quarter throttle. I was considering backing out some of the timing. I just thought it shouldn't be necessary as I am running 93 octane (not 91) and I live about an hour away from Diablo Sport so I thought their tune would work perfect in South Florida.
