Thats probably what happened, is that I didn't get the update. No big deal or anything, I was just something I lived with. I'm sure if I buy another JB4 the software will be up to date.

So do we have any dyno figures specifically for the M50i? You are saying 30-40hp???


2020 X5 M50i - on order. ETA Jan 2020.
