That doesn't suprise me, which might support the total 15 degrees retard that MSD claims (even if it is some tech head reading off the manual).

Since day one I've been using 2 psi as the threshold and 1.5 degrees/psi as the slope. The only change I'm contemplating is going to a 5 psi thresh. That would have the MSD retarding 11.25 degrees @ .8 bar, which should almost perferctly negate the added 12 degrees static advance.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
