edge boost numbers bogus????

i run the hot juice and have always seen around 36-37psi of boost on my monitor at any hard pull, well i installed a autometer boost guage and found a very different number, i drilled it into the air horn like its supposed to be and now i see numbers like 46-47psi on hard runs, whats up with these numbers???

Doesn't the Juice get it's boost reading from the MAP sensor? What is the MAP sensor's limit....somewhere right around 40lbs?

I have noted this on other posts. Except for the EGT readings(if you install the pyro sensor) all Attitude display readings are from the ECM. I am pretty sure the boost number is after fooling and AK RAM is right that the MAP is electronically limited in how much boost it can accurately read. I therefore do not trust any of the backdown or protection features. I keep my eye on my Autometer gauges pretty close.
