" Well I know the N55 is running a different Injectors (not sure about other fueling system components), just presumed that without meth you're approaching the max capacity of the OEM fueling system. I also know that a few N55 owners that have tried the N54 LPFP upgrades are seeing fault codes on their iDrive screen.
Regardless, greet numbers -- Eager to see some Pump Gas & Performance Numbers (1/4 miles, 60-130s) "
Trims can be whatever you want them to be with a back end flash. Fuel pressure on E85 only will likely require an inline pump. On E85 + meth, zero issues so far on a 100% stock fuel system. Not unlike many N54s running around at 500rw+ on E85 + meth on a stock fuel system.
Is the n55 the same as the n54 in terms of intank fuel pump? Can you add a 255 just like that? "
