Thread: Should altitude effect MAP values?

Started scanning for the first time to begin tuning with the PT. I know I should have my MAP (kPa) values going up towards 100 - 110. However, I am not going past 42. Does this make sense considering I live in Denver at 5400 feet?

Or might I have a vacuum leak or something? Posted this as DHP forums with no help at all. Thanks.
