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

to be honest didnt realise it would vary that much

but your right i cant feel any difference...

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).

      What brakes on R34 GTT(Europe)

      I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.

      Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed

      What brakes on R34 GTT(Europe)

      Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
