I'm having a problem with the car backfiring under a heavy load. If i come to a stop and nail it the car boosts up and as it gets to the first second shift the car backfires thru the exaust. However if I gradually get on it from a roll and hit full throttle/full boost the car runs like a rocket. The boost is the same in both cases. Now Im thininking it may be the pump not keeping up, I changed it about 3-4 years ago, think it is a walboro, not sure though. The problem just started this year, Ive only had the car out 3 times this year. Any other ideas........... Im running 50 pound injectors, 48 psi fuel pressure line off, boost is set at 23
