My 2012 f550 has no power on take off it takes forever to get up to speed it's like it has no torque at all and slows way down when pulling a hill with a load I can't figure out what's wrong with it any help would be greatly appreciated

Most chassis cabs trucks are not rated at the same HP/TQ as the pickup trucks.

Did you buy this F550 new??

No it's used supposed to have had the turbo changed last year

Did it drive just fine till recently?? Or has it run like this since you started driving it??

Inspection of the turbo and piping is where I would start pending your replies.
