[Loosing Boost R32 Gtr]

It only peaks at about 6psi... last night it actually peaked at 4psi! But today its back to around 6psi...

The vacume side of the boost gauge is also dropping... im not sure if that means anything in particular...

if the vacuum side of the gauge is droppin to its ur gauge. get a new gauge.
