I have new walbro 255lph fuel pump,440cc injectors, safc2, the car is bogging alot, I don't think there is enough fuel pressure there. the idle is rough and the fuel pump I've notice is quiet when I start the car and I thought they are suppose to be noisy. I don't know whats going on. Plus when I blew my original motor there is a lot of oil in the exhaust that been sitting there for 18 months.

 

i know its dumb question but need some opinions
