Another thing to check
Once a year I do a under chassis audit from a pit on my MH with a Freightliner chassis. This year I noticed the tube going from the outlet of the turbo to the air to air intercooler on the radiator ha...

I am AMAZED. 27 psi with a QUARTER sized hole???? You mean a quarter inch or a quarter as in $.25 ? If you mean the latter, that is an amazing turbo.
I might have stretched by saying it was quarter sized but it was at least as big as a nickel.
Well,
That's still phenomenal that its building 27psi boost with even nickle sized hole. Turbos are pretty good air pumps but, to be able to put out that must boost, with that sized hole, wow, that's pretty good. Now, the first thing I'd do is, remove that entire tube for a complete, full length, 360 degree inspection which, includes areas under where the hoses clamp on. If that hole is the only one and the rest of the tube is in great shape, that's no big deal at all.
Depending just how thick the metal is, it might be possible to TIG weld a patch on it. If it's too thin for that, you can still BRAZE a patch on it which, uses was less heat and the thinner metal should withstand that kind of repair. Then, your tube is as good as new. Your brazing patch job would cost next to nothing.
Now, some might not be comfortable "patching" that tube. But, in all reality, there's absolutely nothing wrong with that. If you patch a hole, you save the tube, the engine still runs at peak performance, no big deal. You just save a bunch of bucks by not buying a new one. Your choice.
And, when that's all done, I'd definitely inspect any other areas of air-transport in that CAC system. Good luck.

On edit: I might have assumed it was a "steel" tube which, you could "Braze" on. But, if that tube is aluminum, and its really thin, a TIG weld is most likely the only way to apply the patch on. It's been a while since I messed with mine so I've forgotten the material it's made of.
