AVCS is 25 degrees at 2400, tapering to 0 degrees at 4800.
The latest tables seem pretty reasonable. I'd subtract 2 degrees across the board, do a couple pulls, verify it's not knocking, then try the tables shown. Then again, with your forged pistons, you can probably afford to be less cautious then me.
How much power are you making? TMIC or FMIC?
