I am at 565 feet above sea level. Most of the MAP HG's I've checked have been around 28.6 at idle. Within 30 miles I can be at 3200 feet. I use this drive to test the MAP sensor at a steady throttle. It should be down around 25.5 HG at this height.

I noticed that your MAP HG was down between 9 and 12.5 with your throttle open percentage around 10-12 %, and the engine RPM between 600 and 900.

It only increased to over 28 HG. When you were on the throttle.

ABSLT TPS(%) 65.9
CALC LOAD(%) 31.4
MAF(LB/M) 10.70
MAP("HG) 29.2

This makes me think it is hooked to a ported vacuum source, wired wrong, or out of range. 9 to 12 HG readings should be somewhere between 6000 to 8500 feet above sea level.
