What could cause this? I have a eboost2 and still have an autometer vac/boost guage hooked up also. I noticed after getting the car done the guages read two different readings.. At idle the eboost is reading -11(seems a little low to me?) vac while the mechanical autometer guage is reading -15. They always seem to be a bit off from one another... The guages are both sourced from the same point also... Any ideas??? Which one is the one I wanna go by? Also what should vac at idle read on a turbo car?

Vacuum at idle is just like any naturally aspirated engine. It depends on the cam specs as to what the idle vacuum should be.
Not sure whether the eboost or guage are more reliable source, though.
