tru-boost question

[99 gst spyder]

I bought a tru boost from a friend, and I'm wondering if it's working correctly. What are some signs of it not running right?

My vacuum is usually lower when in gear and not on gas around 19-20, but when in nuetral, it sits at around 12-14 idling. My wastegate spring is 1 bar and it is rate for 14-15 psi. I routed everything to run the spring rate psi only and zero out my tru-boost.

On any gear, the gauge seem to read right on how much psi I'm boosting. It'll go to 14-15 psi with a hold until I let go so I know that's working.

I just want to make sure the tru-boost is working before I take it to the dyno.

Your vacuum with your DKS cams is normal. It's higher in gear probably from decelerating which pulls more vacuum.

Also it's very tough to determine if your Tru-Boost is working if you didn't even actually try to use it and just set it to run WG pressure.

Thanks. I'm not sure how to adjust the truboost and will not try to due to untune mods plus I don't liek untune wot. What you said is more of a relief. Like I said, It holds and reads boost perfectly. I'm just gonna assume it's working but while dynoing, I'll just have to bring a extra boost gauge and MBC just incase the tru boost is not working properly.

I know how to set it up and everything, I just don't want to make any change.... It's all setup and also zeroed out.
