I'm getting a custom chip burnt as we speak and the burner needs to know what spark advance to try for WOT. I'll be running an MSD boostmaster as well. Mods are in my sig.
Thanks for any help guys. I'll be running 10#s of boost by the way with SVO 24# injectors

Originally my TPIS Level V PROM was burned with 24 degrees of advance, for a total of 30 degrees with base timing set at 6 BTDC. I discovered very quickly that I could run much more advance than 30 degrees, so I had the PROM changed to 30 degrees. With my adjustable timing module, I set my base to 8 BTDC or a total of 38 degrees.

Because you'll be using a BTM (I can't imagine why you'd do this, but that's another issue), go for an aggressive advance and have the BTM retard timing.
