Fuel Pressure Question
#1
I have an 03 SSS with a return style fuel system. It has the stock intank pump and a magnuson in line booster pump. I recently installed a pressure agauge and it shows ranges from 65-72ish. This seems high to me as I thought 58 was normal. I changed both the pump and regulator and the same result. Is this a sign of a problem or is it fine? My wideband shows correct AFRs for a supercharged truck (11.5ish at wot and 14.7 at idle).
Thanks
Thanks
