Is your Kpa value at WOT dependent on altitude or should everyones car have a Kpa reading at 100 at WOT? Reason I ask is because I never get out of the low 80's at WOT, but i'm also at 5200ft elevation. Was always curious about this one. Thanks in advance.

MAP kPa can not exceed barometric pressure. At sea level, the "standard" barometric pressure is 29.92 "Hg = 101kPa. In Denver, at 5,800-feet, the "standard barometric pressure is about 25.0 "Hg = 85kPa. Your MAP can never read over ~85kPa in a normally aspirated setup.
