Default Checking Motorola 2.5 Bar readings?

I've wired the sensor to my LM1. I was wondering what reading are you all getting at certian points. At idle in neutral, I am getting a reading of .97 volts. If I start boosting, I get reading of over 5 volts (I'm only boosting at 4 psi or so, for right now). I read the spec sheet and it says that the operating range for this sensor is 2.9 psi and upwards.

Any ideas?

Anyone have any further info on the 2.5bar? I'm looking to simply tap in and use the data for logging into my LM-1. I know the sensor is linear... but i'm looking for aproximate Voltage to Vac/PSI rates so I can create a readable gauge in the datalogger.
