I'm on a lease currently on JB4 probably going to BM3 when it launches.
My reason, I'm a bit fed up with removing the JB4 physically for dealer visits. Also keep reading about the smoothness of the BM3 over the JB4 (not that the JB4 is bad and is jerky or anything).
At this point i'm also considering a JB4 backend flash.
I'm still thinking about this BM3 a lot and will probably still get it !
Both are good options and will give you lots of additional power.
Fyi on my previous 230i (which unfortunately got totalled) with JB4 and intake only, on map 5 (+6psi) with octane booster (total around 100 octane) I managed 13.09 1/4 mile and was on my way to high 12s.
