under powered/ cant tow anything

so i hooked up my 99.5 7.3 for the first time the other day to tow our 17ft fiberglass boat. Its very light, i can roll it around on the ground by hand on its trailer with some force. My truck barely buzzed up the hill with it attached, even while im not towing, it hates hills, and i have to hammer it to make it up any of them. Yesterday i loaded 1 ton of pellets in the bed, same issue.. chugged up the hills.. and none of these are major grades.. but you would think i was trying to drag the titanic.. my truck doesnt seem to be building boost properly when towing, it got around 5lbs. up hill loaded.. barely touches that on hills most of the time.. on the highway itll hit 10-15lbs normally on flat land..

mods: 4 inch straight pipe exhaust, ts 6 pos with pre loaded tunes, intake.. mostly stock truck, 181k on both trans and motor.

are these 99s crappy for towing? or is there an issue!?

when i looked at my turbo, the waste gate was totally removed.. as in the bolt holes to attach it are there, but no waste gate

seems as if it shifts too early when im trying to go up hill quickly, and then slugs up hill

overdrive switch doesnt work at all

no check engine lights

no white smoke aside from cold start itll spit a little puff

any insight? cause if this is how its gonna be im gonna need to buy a newer model stroke

I'd check your map sensor( its over on the passenger side up by the fire wall, has a little rubber hose that runs over to the turbo) make sure the boost line is still hooked up to it. Also pull your intake off of the turbo and make sure that the compressor wheel is still in good condition with no chunks or wear on the blades. Your truck should yank that boat around no problem. Not having a waste gate has me wondering... Taking it off is no big deal as long as its done right.

There's your problem. Get some 1/4" fuel line and hook it back up. With out that the PCM has no boost reference to add more fuel.

BTW what did whoever that took the wastegate off do with the lines for the wastegate? Did they they take them completely off and plug them? Or are they just unhooked. They will be the colored ones (red&green vacuum lines) if they are even still there

Not as much as not having the boost line from the turbo to the map sensor. But depending on what's missing and not plugged could cause a boost leak. Can you take a picture so I can see what's going on in there?
