What is considered maximum boost and manifold absolute pressure?

[Zoomschwortz]

I have a stock 2006, 5.9 with 32,000 miles. I installed an Edge CTS2 monitor and after turning on the alerts, I am getting manifold abs pressure alerts for 45 psi.

What is considered is considered to be maximum manifold abs pressure and what is considered maximum boost on a stock 2006 5.9?

Thanks

Stock will build 32 psi of boost, which at sea level is nearly 47 psi absolute.

Thank you very much!
Have a great night.

My truck is the same as Ken's, though with four times the miles, and my CTS2 monitor is also showing an alert for max abs press. @ 43 psi. Oddly, this had never happened until recently. One would think, during 30K miles of trailer towing all over the USA, such an alert would appear at some time. Didn't. I wonder if it is possible to accidentally reset the alert? Doesn't seem likely. Nevertheless, I will reset it and stop worrying. Thanks AH64ID.

I adjusted my alarm to 47 psi and then started getting saying 0 psi.

After shutting the engine off, I unplugged the OBD for a few seconds and then plugged it back in.
I then turned the ignition to "Run" and waited until the CTS2 came back up. It ran me through the initial startup menu and all of my alerts were where I had previously set them. Now the only time I get the alert is when it hits 47 psi.

I may have stopped worrying, but a question remains. With the appearance of the max abs press. alert the thought occurs to me that it may be giving an advanced warning of an impending waste gate solenoid failure. Am I on to something, or have I just shown my pessimistic side?

After re-setting the alert I decided to test it, and to charge the truck's batteries, by giving it some exercise after sitting silent for a couple of weeks. The alert is set @ 46.2 and sure enough it sounded when I mashed the go pedal, though the alert window never appeared. At least the batteries are re-charged. So what did I learn? It's time to start probing the OBD port for code numbers. At least the batteries are re-charged.

OOPS.

No DTC codes on the Insight CTS2 monitor.
