which boost gauge do you look at?
your your original(autometer, greddy etc.)
or the one on the Profec.
I'm getting different readings, my autometer says 20psi and the prefec says 189, not a big difference but not perfect.
who shall I trust
another thing, did you T into the manifold pressure for both gauges?
I got lazy and "Teed" into the line that was already in the car, wondering if that would cause a prob.
TIA
