2015 Envoque turbo problems

[seineman]

I carried my car to the shop because of lack of power. If you press the accelerator hard, rpm goes between 4000-5000 rpm and JC at doesn’t accelerate quickly at all. The car drives fine as long as you don’t need to accelerate quickly. The shop stated that the hose had come off the turbo and that it also had a knock sensor bad. They fixed these 2 things and the turbocharger is still not putting out any power. They stated I needed a new turbocharger. Price was astronomical. My question is, how much trouble is it to change out the turbo and could we be dealing with another issue?
