Turbo gauge question
 

Is turbo gauge suppose to be at zero when in idle?

This is probably a dumb question but i ask because I've seen them at 0 when idleling and mine is all the way down.

It should actually be negative, And go up to 0 or just below when you blip the throttle. N/A motors run on vaccum (negative pressure) all the time, And your turbo should while cruising or accelerating slow at low rpms. If its making boost at idle you have some sort of problem lol.
