Welcome to the forum!

Did anyone ask for pictures? OK - understood - Friday is your last chance... or we'll cut you off the forum.

The boost dash gage is not that accurate, but will give you a good idea of boost levels; at least on/off feedback. Depending where you are (elevation and temp), boost levels and gage indication vary on a "perfect" car. As you say, the "butt dyno" is important too, but need to consider that different cars feel differently under the same conditions. Unless obvious, and if so, something is wrong - as you believe.

There is a very simple test for the WG, just put a piece of cloth/paper towel inside the WG exhaust pipe and have someone looking when the pressures pushes it out; normally you'll have to be under boost for it to happen. If it leaks - depending on the magnitude of the leak - it'll push it out without any gage indication. If it doesn't leak, the WG should start opening about .6 bars - you'll feel the boost and should have some gage indication of it - and at the same time you should see the cloth/paper flying away behind the car... Home made testing but it will give you a good indication of the WG condition...

BTW 930s came with single outlet exhaust not dual. Did anyone say mods??

Enjoy the car and be safe!!!
