The Bat reading on my scanmaster is dropping from 14 to the 11's when I start to get into boost. I first noticed it at night when the headlights and interior lights would dim at 15 pounds of boost. I have a feeling that this happens at the same time my SMC kit starts spraying. Any ideas? I am seing a few degrees of knock at above 15 psi and I suspect it is related to the fuel pump not getting enough voltage. The battery and alternator are both new and I never see less than 13.5 Volts during normal driving.
