You can still put it on map 0 when you get to the dealer. I read somewhere that map 0 can cause some fuel oscillation if driven hard but I have actually driven on map 0 for a whole day (forgot to switch it after I did some coding on my car) and it was perfectly fine. My appointment is coming up in a couple weeks and i'm debating on leaving it in there. My warranty has expired anyways so I don't care if they see it.

The only reason why I would potentially take it off is because I don't want some mechanic messing up my jb4 wiring or not plugging something back in, etc. I'm not sure what all gets taken off in order for them to get to the bolts but if they touch anything related to the jb4 and then plug the stock sensor back in or something like that, that could cause an issue.
