Hey I am new to the form. Ok I have a 2000 Mustang GT supercharger/intercooled just install a Kenne Bell boost a pump now my fuel pressure gauge peg at 100% and my car I running lean. Help.
Yes and you are right it should be rich but the fuel pressure may have some thing to do with that too my air not Anough gasIf 100% is 100 psi, that's way too much!
I would think that the engine would be running extremely RICH!
Did this problem start when you installed the boost-a-pump?
