F.A.S.T. QUESTION

I JUST INSTALLED A F.A.S.T.BANK TO BANK ON MY 87 MUSTANG WHICH SPORTS A STEVE PETTY BUILT 360CID VICTOR JR HEADED ENGINE WITH A T-TRIM. SHOULD I LOCKOUT THE MSD DISTIBUTER SO THERE IS NO TIMING ADVANCE AND LET THE F.A.S.T. CHANGE ALL THE TIMING? ALSO IM RUNNING THE FUEL PUMPS VIA THE BLACK WIRE COMING OUT OF THE F.A.S.T. UNIT( WHICH IM ONLY USING THIS WIRE TO GROUND THE RELAY)WHEN I SHUT THE CAR OFF THE F.A.S.T. WILL BUMP A MOMENTARY GROUND SIGNAL TO THE FUEL PUMP ABOUT 5 SECONDS AFTER I TURN THE IGNITION OFF, ALMOST LIKE A GROUND SPIKE. HAS ANYONE EVER SEEN THIS? THANKS FOR ANY HELP IN ADVANCE!!
