im running 1 bar boost on a 99 c5 with deka 60 lbs injectors and the lingenferter pump, that came with the centri kit (i believe some incarnation of the walbro 255). as fp is dropping from 67 psi at idle to 48 psi i installed a the racetronix harness. i cut out the bap connector shortening the thin wire to a minimum and ran an additional 10 mm2 ground to the battery. the effect is zero. the honeywell sensor logged 1.77v before and im logging 1.77v now. although the pump apparently only pulls around 10 amps this is contrary to my previous experience and to what would be expected.
any thoughts on that?
(otherwise everything is stock, returnless system, filter/regulator new.)
