1 walbro is not enough. 255lph = 63gph. Probably not much more then your stock pump...if any. You need upwards of 80+gph. For 400whp I would shoot for 100gph+ just to be on the safe side. Iv never tried an Emanage on a Bimmer. Iv heard tons of people say they wont work, SAFC's wont work, but nobody has ever said "yes...I did try it, and it did not work". I think everyone just assumes it wont. Kind of like the monkeys in the cage. The one monkey gets his a$$ kicked for trying to eat the banana, and none of the other monkeys know why there kicking his ass.
