A/F readings on my S300

i actually think something is wrong with my map sensor? for some reason my a/f only reads at mBar 650 - 869 all across the rpm range, even at idle it's siting at Mbar 650 which i thought was wierd. This is with the b17a cams in a b20vtec. I've always assumed that idle was between the Mbar 127-417

You think there is something wrong with my map sensor to only read in that range, or mechanical or something with my S300 settings?

i figured it out, i was getting a vacuum leak from the throttlebody gasket.
i was wondering when i start the car why is the map sensor showing 1000+mbar
after i fixed that the engine is behaving a lot more consistant :)
