I recently have noticed a light "clicking" noise when in in boost, from around around 2-3 psi and up. Comes from the right passenger side of car. Any thoughts? Sounds like the noise a heater blower makes when a little bit of something is it it but this noise is not related to heater blower.

 

Loose turbo pipe clamps? Or air box grommets are toast?

 

Perhaps disconnect something, disabling the turbo. You'll get a code, but if the ticking is or isn't still occurring, you'll have more information.

I would also theorize that if you can hear it through the increased noise of the engine and turbo working hard, it may not be just a light ticking.
