Got my boost gauge fitted today and it drops to -8 psi on idle (see video) and boosts to 0 psi. Ok so it is a cheap gauge from fleabay but there must be something amiss. Have dropped the boost as far as possible on a the bleed valve before it gets setup so should be running near standard boost level.
