2000 7.3 please help

00 7.3 possible up pipe leaking??
I just had new injectors put in with new uvch and pigtails loop s@b filter and 4 inch diamond eye and ts 6 pos with full custom tunes.. truck runs great.. but at higher rpms I get this noise... would that be my up pipes leaking or turbo going out? There is no shift play in the turbo at all

That sounds like the wheel scraping the housing in your turbo. I would pull the turbo and get a look inside it before you drive it any more. You may have caught it early enough that it hasn't damaged anything else.

thinking about it, it might be the wastegate opening/closing

it might still be the turbo wheel barely touching the housing at high rpm's. they spin much faster than the rpm's of the engine and it's possible that it is moving/expanding just enough to make a sound.

or maybe it's the wastegate doing funny stuff. what is boost gauge telling you while that is happening?

Boost Guage stays steady. But before all upgrades was only at 11psi. Now hits like 11psi on all tuned
