7.3 towing sucks

Hey so im new to the diesel world + this site and need some help....
I just bought a 2002 7.3 F350 4x4 crewcab long bed 93*** miles and its a big upgrade from a 150 for towing but i just towed my fork lift (6000lbs + trailer 1200lbs) to a job site and i was not so happy with it. I was cruzin at 55 then hit a little hill and dropped to 40mph real quick then pretty much had to floor it to keep the 40 goin. Then i got to the job and it was a pretty steep hil but not to crazy and going up was a strugle (15-20mph at 2900rpm) I expected the truck to pull the weight way better??? has any one had any problem like this? little more detail the truck is lifted on 35" tires with a 3:73 gear thought it could lose some low end grunt but lose all of it i would hope not. I read some people tow their 40' 5th wheels on 37" tires and 3:73 gears no prob so figured mine would be ok. I didnt have a boost gauge so i dont know what the boost was but now i got one and with no load i see 19lbs dont know if it matters but mor info the better. NEW cam position sensor NEW ICP and NEW IPR valve so what could caust the truck to tow so poorly?

please help ant leads would be somewhere to start thanks
