Quick one (maybe) Squeal under boost

had a quick search around seems could be one of my pipes is loose.

Will a smoke test help me track this down? it only happens at close to max pressure.

It`s not obvious and as far as I'm aware I can`t get it to boost in neutral, or am I just not revving it hard enough?

If someone can wade in - whilst it`s amusing to shoot past people sounding like an out of tune recorder, it really shouldn`t be making these sounds.

I`m also wondering if it could be something to do with the Wastegates not sealing properly, as they`ve picked up some rattle recently.

Will dust off the old kcan cable over the next few days and get an MHD log on boost targets.
