BMS will be making a JB4 back end flash for the N55. Like their N54 back end flash it will load via the Cobb AP and transfer fueling over to the DME side, along with VANOS (and valvetronic?) changes, speed limit disable, along with a little more ignition advance up top when using E85 and/or meth, and other table changes meant for higher HP cars. Maybe another 5-10hp in there maxed out? It's mainly to set everything up for large turbos down the road. The N55 likely won't run in to fuel problems until the 450whp levels the N54 starts to run in to fuel problems.
