Engine/Transmission (1994 - 1998) gray smoke

[DDarmos]

I am getting alot of gray smoke instead of black. I don't think my timing slipped it is at 21. 5. Could it be with the aneroid it was back of years ago could it have changed. How does it work?

Thank you

When did it start to turn gray in color? Sounds like you need more fuel. Mine was gray with the PDR40, before the 370s went in. Gray can mean more air than is needed to burn the fuel.

well I am going to put some 191 dv's in. I know fuel and boost are directly correlated. I am only getting 36-38 pounds of boost. I was getting better with stock injectors and no plate.
