WOT Adjustments dont work at high altitude U7135-9r29

I have a Challenger R/T 2010. I live at about 7700 feet above sea level. The atmosferic pressure arround here is about 77Kpa. I have noticed that the wot adjustments have no effects in the cals. To demostrate this I ran some 2nd gear pulls from 0 to 5200rpm as you will be able to see the timming and fuel curves are virtually the same even I did 3 runs: one with the 91octane with no mods, one with maximum retard and maximun leaning and a third with maximum advance and max fuel enrichment; all show virtually the same curves. To eliminate the knock retard factor I used 92octane fuel+nos octane booster.
Please take a look at the provided tunes but arround the 77Kpa range; not at 100Kpa
Attached you will find an excel file with comparative graphs of the timming and AFR between the three different tunes; also in there are the logs for fuel (taken with a diffrent software, cant log fuel with predator). Also I'll put my original tune and the three tunes Ive been talking about. Finally also attached are the log files frome the dataviewer. Sorry for throwing all this info at the same time.
My final question can there be a crom file that moves the wot parameters all across and not only int he 100Kpa? Assuming that is the issue.....thanks!!!
