Video of Flat Oregon highway pulling 27K

flat oregon highway pulling a total of 27,000# down the road. Shows the lack of power in OD as the speed and rpm and boost drop after the upshift. Notice the boost drops 10 psi and the rpm a 1000 rpm lower at the shift. The boost never goes up after the shift but continues to drop to about 4-6 psi when the shift occurs to once again gain rpm up to 3K and the boost runs up to 20 psi. The EGT numbers never got higher than 1100. The whole time this video was being recorded I never lifted my foot off the floor...max throttle the whole time.
