I noticed a lean condition on the wideband. I verified my base fuel pressure is 43 vac. line off. I taped the fuel pressure gauge to my windshield and drove the car. My boost is set at 20psi and my fuel pressure only went to 50psi at wot.
Should have went to 63psi. My first thought was the fuel pump laying down but I hooked a regulated air sorce directly to the fuel regulator while the car was running and set it at 20psi. The fuel pressure shot right up to 63psi. I then tested the connection of the hose to the regulator thinking it was letting pressure leak by but its not and I tested the other end at the vac. block on top of the throttle body and all held good pressure.
So, what is going on that my regulator isn't getting the pressure to raise the fuel pressure with boost? My BLMs sit steady at 131, so I don't think I have any other type of vac. leak.
