Car tuned for 13 psi. Noticed recently a drop in peak boost to around 12. Settings on the boost controller remain the same.

Yesterday heard a rattling sound coming from underneath the car, had a look noticed some sort of sensor near the cat had come out. Screwed it back in, but remains the same.

Any ideas what could would cause this?

Car runs as normal, idles fine...

Its bizarre considering settings have not changed.

Boost varies on a cold/hot day. Less boost on warmer days more boost on colder days. If i were you i wouldnt be worrying about a 1psi variations. You wouldnt even feel the difference in power
