[pitoturbo]

set your FP wherever your chip maker specifies...usually 42-45 line off

Depending on who made the chip, 42 to 45 psi is probably about right. You believe it is running lean. Do you have a scan tool ? You really must have some sort of scan tool to tell what's going on.

dont have a scan tool / my f/p is 45-48 line off , about the lean cond im just looking at the plugs not even a trace of fuel is that good or bad?
