IF you are running real high boost, and running factory intercooler pipes.Then yes, I would certainly upgrade the hoses adn pipes.In the diesel performance world, blowing tubes and pipes and hoses,due to huge boost.Happens all the time, you will see huge smoke out of the truck all at once, and a loud pop under the hood.That is a pipe off the intercooler or turbo popping off loudly.The hoses going into the turbo, I would upgrade,because if you run high boost, running lotsa air through thta thing...Then it would be wise, to upgrade the hoses going into and out of the turbo,to larger stronger hoses.a bigger better intercooler itself may not be a bad idea, to keep things from getting too hot and kiling you horsepower.
