Default Fuel pressure

Car sits around 58 psi of fuel. But when on it hard under boost it gets to around 40 psi then goes right back up when off throttle. it just started happening the other day. Could my pumps be going out. Driving me crazy

That is classic sign of pump going out assuming you have enough fuel pump to begin with.

Is it running a BAP or no?
