Car runing wayyy to rich

[japSW20]

Hey people,I took the car for a spin and when i get on the gas it just bogs down and clouds of black smoke come out.I jump the 2 pins to check for error codes and the computer isnt throwing any codes? But when i drive off of boost it runs fine?

What is your fuel pressure with the line off?

I have no idea what the pressure is,I think the cars has a aftermarket pump because i could hear it whining loud,How would you go about checking pressure?

Get your hands on a fuel pressure gauge. Hook it up to the schrader valve by the fuel pump. Turn on the ignition before the starter motor kicks in and read the gauge. Brad

Correction- The schrader valve is right by the fuel pressure regulator. Brad

Just a thought, but the last time that happened to me, my O2 sensor was going away. Might want to swap in a new one and see if it makes a difference.
