my sc hesitates at 5 psi of boost and i replaced a lot of parts like fuel pump and fuel filter fuel pump relay plugs and wires and a dis mod and still hesitates does any one have a idea about this please help
 
it hesitates at 5psi but after the hesitation i can get up to 10psi my fuel press is at 40 and idle and 50 under load
 
Fuel Pressure Regulator new?

If not I'd maybe check that, I know you said idle was 40psi and 50psi underload seems decent.
 
How much vaccume do you have at idle? Make sure your vac line is on your FPR. Did you ever bottom the car out in front or have a minor accident?
 
i checked for cracks and none but i saw a small crake in the outlet tube of the sc that might be it i hope that takes care of it
