Merry Christmas guys and gals.
Anthony,
did you do your math based on adding 2 psi to the 34.7 psi your supercharge had been moving (ambient air pressure plus your current boost) or adding it to 20psi? (wrong way) . Not saying you did, but many people forget to factor in the ambient air pressure (14.7) and in doing so, add more boost than they intended with pulley changes.
looking forward to seeing what you find as you explore the frontiers for us : )
