Still waiting on adapters to make waste gate connections on the new 63s('21 M50i). The limited reviews of just the 2 basic air box/MAF or whatever they are called up front haven't been all that great on the lower 4 or 5 lb boost increase maps which I would have expected to be a pretty significant jump in TQ and HP to a slightly lesser degree. Wondering if some of these guys are not evaluating or making their SOTP in Sport plus. Love to hear some feedback etc. on JB4 with these late model 4.4L motors.
