Overdrive/power issue, stumped

yes ive searched, seems as if alot of threads touch the subject then lean a different direction. hope someone can shed some light.

i recently purchased a 99.5 psd 7.3, has 4r100 trans, 6 pos ts chip, 4 inch straight pipe, ccv mod, diy intake, boost/egt/trans temp gauges.

heres the issue, i tried towing a boat the other day and you would think 20 tons was on the trailer, it held rpms, but just slugged up. next day i drove it up a hill and yet again she had a hard time, and this was with no load, no trailer and it chugged up the hill and barely built boost. The previous owner removed the wastegate, as in the whole assemblys missing. It builds 5-10lbs boost normal driving and 22-25lbs under wot with 140 tune.. seems as if it shifts too early and i hear a loud whoosh and there goes my power.. it doesnt like any kind of hill..

my o/d switch doesnt work at all, i bought a new bulb thinking it was the bulb, but when testing it at 50 i felt no shift change or "braking"..

i just recently did oil, fuel filter, trans fluid, 6637 filter

im stumped..

some more info:
right side front hub wont lock so 4 wheel doesnt work
when truck shifts it sounds like it has a bov
back right wheel is hot to touch after 20-30min driving
no white smoke aside from a little spurt when its colder out

Thanks for any help ahead of time, i really love this truck and would love for it to be put to work at 180k

vacuum leak

bov?

hot brake
no white smoke aside from a little spurt when its colder out
good

I would guess the hot brake is most of the issue. If you're constantly trying to slow down, it's hard to build up speed. Just in case the brake isn't the issue, check your rear diff fluid. Being low on that would be bad, but it wouldn't be bad for too long before it's worse. If it is a hot brake, I'm surprised it hasn't been more of an issue, like fire.

With my front hubs locked (I also have a vacuum leak I don't care to fix), I can coast ~3/16 mile on flat ground, slowing from 35 to right around 25.
