I'm not 100% sure that this is a clamp issue. Just figure I'd throw this out there.
A few people in the AP thread for 2015's have stated that they aren't hitting their boost targets. They were advised by various other members to adjust clamps or run the HWG maps. Whether or not the clamps are an issue is debatable since there aren't actual numbers/results to prove one way or the other. Could loose clamps cause a vacuum leak which would lead to lower boosts? Yes. Is it more likely that the environment doesn't require full boost to hit target torques? Probably. Yet that doesn't seem to be what this fix is proposed for as it's more focused towards boost creep.

A smoke test before/after might be worth it however it probably isn't a one size fits all problem. It might just be as simple as certain models not having their clamps tightened properly. Several people have stated that theirs were loose. Regardless I think it would be the wisest decision for everyone who owns a '15 to at the very minimum check all your clamps. If they are loose, tighten them. If you are worried that stock clamps aren't strong enough or want to prevent it from chewing up the hose, replace them. I would imagine the results are negligible and any difference from stock clamps are just a result of loose clamps in the first place.
