P3 Cars Integrated VIDI Vent Gauge
 

Anybody have this gauge with their turbo kit? Does it show boost reading correctly using the OBD port? thanks

It reads the data directly from the ECU which is given by your sensors.
I have one and with the stock MAP sensor the boost level was incorrect.

But after getting it switched by my tuner it was reading correctly.

What do you mean getting it switched? Thanks

I think he means switching out his map sensor to something like an omni 3 bar map

You have 2 options with the P3:
OBD MAP Sensor reading (OEM or correctly mapped aftermarket one)
Analogue boost sensor (which is what I run)

The stock map reads up to 5.5psi. The avo stage 1 turbo kit come with a 5psi wg so can the oem still be used?

I have a P3 along with an AEM failsafe they read the same boost fairly conistently. I am running a 3 BAR MAP sensor.
