Fuel problem, need opinions
Alright I have a turbo D with the following fuel setup. Walboro 255, 880cc, stock fpr, and stock rail. The car has ran fine on 16lbs for about a year. I had the block and head built so I upped the boost to 23lbs and now the pressure is acting crazy. At idle the pressure is at 30 and at WOT it is 42-45 when im boosting 23lbs. The car starts to lean out like crazy about 6k and maxxing out the 880cc. I thought it was the fpr so i put on a loaner aeromotive regulator to test out that theory but, it was still reading the 30 at idle and 42-45 at WOT. My next guess is the stock fuel filter, I have had the same one on the car for a year now. Can a filter lower pressure that much? Could my resistor box be crapping out on me? Throw any of your theories at me so I can figure this small problem out.
