for 550whp ? not sure...
Stage 2 walbro 450 or 550lph with a cooling mod on the EKP, should be enough. Also the DIY guide is pretty easy, and this mod is cheap.
if you street tune with MHD or JB4, Ill check what would be the limit with a stage 2, and then evaluate if a stage 3 is needed. More work, more failure point since it need a relay and a signal.
port injection or meth is always a good idea on a n54 in that HP range.
