98 V70 GLT These boost numbers are hilarious

Something tells me Torque is giving incorrect numbers. In this case, "Something" is a lack of engine parts flying in a cloud around the motor when I put my foot down on the gas pedal. Or maybe 44psi counts as "Low Pressure" in Sweden.

Look at the high-water mark on the boost gauge (bottom left). Everything else appears to be within a reasonable range, and it accurately reflects knowns like speed, RPM, etc.

So what do you think the real numbers are like? Anyone familiar with Torque who can give a hint as to how to fix the indexing of the boost/vacuum gauge?

I'm confused as to why you are writing about torque when referring to the boost? The boost should be - when idle. What is it boosting to when you are WOT?

Sorry, Torque is the name of an Android app that talks to my cheap Bluetooth-enabled ODB-II reader.

You can see the yellow bracket on the boost gauge - that's the low-water mark. The thick white stripe corresponds to current value. The red bracket, at 44psi, is the high-water mark. The thick white stripe indeed goes up there and the numerical reading says the same thing.

I am just guessing (just a guess, mind) that there's no way boost ever gets that high.
