Unresponsive boost gauge

[SEAN-NZ]

would be much easier to read in english lol, but just so i understand correctly, bov line goes straight from intake manifold to bov, and the line for wastegate is the one that is before the tb, if thats the case thats what i though anyway

[Davezj]

Yes,
the bov should be direct from the inlet maniflod/plenum chamber, and the wastegate goes from the inlet side of the throttle body but also connects to the factory boost control solenoid valve.

thought that was the case

so i got some vac line to go direct from intake manifold to bov, exactly the same issue, no better, next thing im gonna try tomorrow, use the vac line i got and ee if i can run that from t piece to boost gauge and see if that helps, hoping it does

[Davezj]

Don't forget to check the T piece itself to ensure the branch that goes to the boost gauge is the same size as the straight through diameter.

Ok, will check that

well im an idiot lol, turns out when i taped up the t piece to make it seal better with the vac line that i actually almost compleletely blocked the hole on the manifold side of the t, take the tape off and use zip ties that i just brought to seal it, problem solved, gauge it now really responsive, easier to see the boost go up and down as i go up in the rev range, might be an issue there, and pretty much instantly down to about 25 inched of vac when i take foot off compared to a second or 2, so glad i sorted that out, feel a bit stupid blocking off the hole in the first place
