Running rough with my GTM SC...

Voice59

I have a GTM 1.5 SC on my Z. With an innovate boost gauge I believe. This may be a stupid question but I've noticed that my boost gauge stays at a vacuum for the most part which I believe is fine, but when the bypass valve closes it doesn't go to high over 0. Is that correct? Or is there supposed to be some kind of actual indication?

I've got the gym st2 sc with a defi gauge. Same as you, mostly in vacuum, but to build any boost you have to be WOT and build the revs... If you're almost at redline and full throttle and it isn't showing any boost, then you have an issue somewhere.

Ok. Also I have a bypass valve that blows ridiculously loud at idle and little to no throttle. Is that normal? Can I quiet that down?

That is normal too.
