I set my base pressure and removed gauge, been driving fine in weeks since I did that. I installed Innovate dual wide band to monitor (was planned anyway), and my lambda values hold just fine, under max boost high rpm they are ~0.75, so no reason to think any issue with fuel pressure.

Guess my theory is since the FPR leaks down when off, perhaps an air bubble gets between the gauge and causes low readings.

Anyway, thanks for inputs

2+2=4; 2+0=2; 4>2 : 2+2 > 2+0.
