Monitor boost advice
 

Could somebody please point me in the right direction as to how to accurately monitor boost?

I have a discrepancy between the gauge and torque app.

I would like to log a few full boost runs and see what the actual boost is.

Cheers for any help.:)

The torque app should be most accurate as it is reading what the ECU sees from MAP sensor (beware it is not a Subaru specific program so may not be entirely accurate)
ESL do a great log mapping program:
Try emailing Andy Stevens: andy@enduringsolutions.com
It will read boost pressure from the MAP sensor input into ECU and is designed for Subaru ECU so should be THE most accurate

Our software and datalogger only works with ESL ECUs currently.
