I was really hoping the jb4 would work on my x5m cause if I had an issues with my truck it took 15 min to remove. I've now been looking at VAC motorsports tune, that's like the jb4. They say that it makes power on the dyno and it can be removed before dealer visits.

I always go to laurel BMW and I don't know how'd the feel about a tune on this as far as the warranty goes.
Have you since tried again with the JB4? I've got an ESS tune coming in the mail now, but I'm reading some M5 threads and they're getting equal if not more power using JB4/meth/stock tune vs aftermarket tunes.
