Boost Gauge Issue Or Worse?

[danbevsta]

Hey guys,

Installed my boost gauge into the right side a/c vent in my r32 on the weekend and notice something that is starting to worry me.

Before the install, my gauge was sitting above, as pictured bellow,

When it was up on the suction mount, it was reading full boost @ 13psi. (I have a boost T).

now since I've moved it into the ac vent,

I notice the car is running at 17psi full boost.

I tried to lower the boost on the boost T and notice the regulator was already wound all the way up (So stock boost?) and I'm running 17Psi.

So, pretty much was getting 13 psi before relocation and now 17psi on same settings on boost T.

Could that be just a faulty gauge? I also notice when the cars off it sits at 5psi (as above).

Any help would be appreciated.

Thanks!

gauge is fded. Isn't that obvious?

either that or climate change is getting serious!

Im new to the turbo scene, I thought the gauge could be accurate and there could be another issue causing the pressure to be running that high.

Oh well, thanks for the help

fair enough. To put it another way if your speedo was showing 20kph when the car is off, that would also be wrong.
