Map kPa values at WOT at altitude

Need some clarification on a how my MAP readings should be at approx. 5900 ft. My datamaster logs are all showing my max MAP readings of being ~85 kPa. Now I understand (or at least have a decent picture) of how altitude robs power. But I was under the impression that at WOT I should be in the 100 kPa range by either defualt code in the mask (8D) or by sheer science. Now according to this post https://www.thirdgen.org/techbb2/sho...hlight=map+kpa I assume that to be true. The problem lies with my WOT I feel like it could be better (dont we all) with the mods I have. Almost seems like she is holding back a bit, if you catch my meaning. So would more tuning be required in the 70-80 kPa range to solve my WOT problems or is it more important to figure out why the kPa range nevers gets to the 100 range. All opinions and responses welcomed.

MAP is absolute pressure. Best you can do at WOT is what you see at key-on not running (baro). Forced induction aside and not dropping in elevation as you drive.
