Meth and timing

[insane]

I have a .060 shimmed head and arp head studs. I am running a stage two s/c with 13-15 psi with hurricane's meth kit. Can I add timing at the big end and what is the most I can add up through the rpm's. Has anyone used their map sensor to add or pull timing per lb of boost?

I would not add timing.

X2, but you will get away with running stock timing.
