    what i have found...
    the cylinder heads that require more timing, in natural aspirated state , require more with boost
    ie:
    sbf's generally use LESS timing than sbc's
    soo same with boost added

    I would start with 10-12 degrees less with 15 psi.

    Mopars like 36 to 38 full advance. I am planning on locking mine at 32 and pulling 2* per pound of boost up to -15* to be safe with the MSD BTM.
