Bypass the boost pressure switch. Check the voltage out put from the BAP it should 17 volts to both FPDM's. PA Alternator makes larger pulleys for these alternators. Before you do that let's do the above and then let me know what you find out.

If everything checks out with the above I think we need to get you a tune from Lund Racing as we previously discussed.
