OK, so my stock gauge doesn't seem to be working right. Usually my defi and the stock one will hit 0 at the same time, which is a good indication to me that things are working. Now while the defi is at 0, the stock is still way below. Stock one will get over 0 eventually but not by much. I am concerned because I am thinking that the ECU is only giving fuel for the boost the stock gauge is reporting. My wideband says that things are OK, but that sensor is really old...
In this situation, should I just get another boost sensor and see if it fixes itself?

The ECU gives fuel according to what the MAP sensor is reading... I dont know if the stock boost gauge gets it reading form the MAP sensor or not...
The map sensor has nothing to do with fuel, only timing on an FC.
