Saw some info you posted on barometric pressure readings in our map sensor. I?m having an issue that I can?t figure out. That key on my car Reed?s correct barometric pressure at 14.3 which is exactly what it is today. As soon as I get on the throttle and hit roughly 9 pounds of boost, the barometric pressure sensor changes quickly to 15.0 to 15.2. Obviously I haven?t changed altitude or weather pattern. I?m sure this is causing havoc on fueling once I?m WOT. Any idea?
