I would try the 045 curve first. The choice of max advance is yours. I suspect that you will be able to run with 43 degrees without pinging. For my pinging tests I filled the tank with 50% premium and 50% mid grade. That gives me some safety margin as I normally run on premium. I gave it WOT at various rpms in 5th gear. If it going to ping it will most likely be in the 3000 to 4000 range.

You probably don't need the 006 tuning curve unless you have long duration cams.
