    Boost Gauge negative at idle

    Just a quick question…I’m running a dynotune boost gauge.
    At idle 1800-2000 rpm I’m getting a negative reading of 10….at about 6000 rpm I’m getting about 0 boost…[email protected] 8200rpm its showing 10.3.



    Is it normal for it to go that low in to the negative when its idling?

    yes , your drawing vac then. At cruising you won't push much but zero doesn't sound right. Under load is when you push boost.
