GlowShift boost gauge response

- How responsive are the GlowShiftboost gauges? If I'm not mistaken, aren't they stepper motors?

I ask because it seems I should be reading a few PSI at idle (being full factory emission system). If I give it a quick stab in neutral to 14-1500, it will jump the gauge quickly to about 9psi then quickly return to 0. I haven't taken the truck out yet to see any other readings so it very well may be fine. At a low idle (although I havent verified with Insite yet) you can def hear the turbo whistle which is leading to the conclusion of it generating a few PSI.

FYI, using the port on the top the intake manifold (right behind where the EGR pipe comes in).

Thanks guys

What did you run from intake manifold port to the gauge -
if it's tube then gauge is just regular manometer
