Car stalled again today with cat light on so I've turned the boost down to 1 bar just to see if this makes a difference later in the week, also is it worth fitting new 02 sensor?

Hard to say without more data, really need be monitoring O2 sensors air flow etc to get idea what might be cause .
still could be electrical gremlins
when it stalls does it gradually deteriorate to a stall or is more instant with no noticeable running or idle changes .

Instant stall, but starts up again but can stall again etc leave for 5 minutes and drives again, I've turned boost down for now in case its over fuelling, having a day swapping sensors and soldering Mafs this weekend
