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
