Rumor I have heard is that they are going to replace the baby turbos on the X6 50i with larger turbos and with a simple tune HP output can be north of 600hp. I believe Garrett Turbchargers may already have ones that fit. I can't wait until Steve Dinan finally gets around to it because I will have my littles turbos replaced with these and then have him tune the boost output and turn my X6 into a real monster
