Would someone please tell me what extras you have to have on hand to make the ME-R work? Not necessarily to fine tune but to function. I am aware that the wideband o2 works well with it but do you have to have it? I have already asked these questions on the ME board. I may have overlooked it on the ME website but even on the price of the ME-R it just says "around 600." What am I getting when I order this system? My ecm has been modded for low imp drivers. Is there anything else it needs? Should I go with the extender chip and ls1 maf?
