2001 7.3 turbo question

I have the 01 7.3l F350 quadcab with 175,000 miles. Lately the lag from start is getting worse and I cannot hear the turbo whistle hardly at all. I also cannot hear my wastegate. Does this mean my turbo and waste gate are going out? The lag is pretty big if I step on it but a few seconds later the turbo does kick in and has power up to 12psi. I want to hear my turbo whistle. if it needs to be replaced what turbo would you all recommend? and should the waste gate be done at the same time? thanks for your expert advise.
Frank.

I do not know if I have a boost leak. I know there is always oily dirt on top of the turbo tubes near the Y. I cleaned them once and they are dirty again.

I am a bit new to a diesel so I do not know what the up pipes are, sorry. I only had this truck for two years and it is my first diesel.

The up pipes are the pipes that come off each exhaust manifold to move the exhaust gases to the turbo. Pretty common for them to leak.
