I don't believe Dinan has cracked the new ECU yet, or else I'd consider it. But I have not seen or read any issues with the JB4 though. And at this time, the JB4 seems to be the best dollar to horsepower unit out there that actually works. Once the new ECU is cracked, I might switch. But for now, I am okay with this and along with the other thousands of the boosted BMW owners out there that use the JB .
OP, not to rain on your parade. When you break something and need it to bring it to BMW for service, just remember that your VIN may very well be flagged (whether you take out that piggy or not) and you might run the risk of voiding your beautiful new car warranty. I have seen it happen.
