you need somthing to tune you 450cc injectors to the stock ecu fuel map specs. you can run a piggy-back system, or dsmlink. your pump is probably fine for now, but what are you trying in the future to do? for $90 you can get a walbro 255, and use vfaq to install it. that will supply alot of needed fuel/hour rate for anything you want to do in the future. as for your flow, your kinda limited with the 450cc injectors, are they high or low impedence? i would suggest reading flow charts for those injectors. then sit down and think about how much realisticly you want to spend for the HP, read a bit more about fuel delivery. your gs moator will run your injecters, but its probably going be running rich, and you'll probably burn your plugs and wires out fast, not to mention idel rough. but first of all what are intentions?
