Do I have a low boost problem?

UPDATE: I got the new PID code for the ScanGuage D and now it shows full boost pressure. However it only shows in whole numbers (the other reading showed tenths too). Maybe ScanGauge can fix that.

But I'm seeing up to 46 psi boost now. So that relieves my concerns.

I e-mailed ScanGauge again, and they sent me a new PID code that will display the boost in whole numbers with tenths (X.y psi). What a great company and fast response time.

Today driving up the hills in NC, my ScanGauge D shows engine load at 99% and boost at 31.48 psi.

Should I be getting closer to 48 psi at max load?

I don't remember ever seeing mine, even that high on the OEM digital readout..
Don't even know what max. might be.

The C13 Acert engine is twin-turbo so 46 to 48 psi max boost is normal.
On a single turbo engine (your Cummins) I think around 36 is max.
