normal for a boost gauge to do this??
i have an AEM analog boost gauge. everything is installed correctly and works perfect. i noticed the other day driving around, while sitting at idle my boost gauge reads about 1 psi of boost. the slightest tap of the throttle and its hit 5psi quick, then it takes a little more gas to get the psi up like normal. so is this normal with my kind of mods? thanks

i understand that, thats why im trying to figure out what might be causing the gauge to read that way.
i T-d the vac source from the vac line going from my intake manifold to my BOV.

Positive vacuum when not in boost? I almost fell off my chair...
To the op: while sitting at idle the gauge should be reading vacuum. Depending on cams and so on, more vaccum or less ... But VACUUM. Touching the throttle should take you to some boost pretty fast but just "blipping" the throttle real fast should maybe get you to 0, not +5psi. If your car is turned on and idling and your gauge is reading 1psi of boost, that's incorrect.

still, vaccuum should be read around 20hg (at least mine does) at idle, and as stated above, any throttle should bring you close to 0 or exceed 0. sounds like your gauge is brken. try and reinstall it w/ a different tapped source and see if the problem persists

thanks for the responses guys. im pretty upset to hear that my $150 brand new AEM gauge is most likely broke. i guess ill contact the vendor i bought it from. its gonna be a pain in the a$$ to work off even less wire when wiring up a new gauge
