boost gauge flutter? turbo apex

[big bear-apex turbo]

i recently did a custom turbo kit on my 06 apex and have been testing it out lately. i notice as i gain boost the boost gauge flutters up and down abut 1psi really fast. i do not have a BOV but it runs excellent. any body know why it would do this?

where do you have your boost gauge tied in?? to the inter cooler or throttle body's?

right off the discharge of the turbo

I found the steady place pull vacuum is from the Throttle Bodies.

You need a liquid filled boost gauge and this will all go away, and to also pull from the vacuum lines.

oh okay so i should connect it to one of the unused nipples that are on the throttle bodies?
