My question is, can the stock n/a ecu successfully handle the increased injector size when operating in closed loop, or will it run pig rich? If it will run very rich in closed loop, what about the possiblity of running the stock primary injectors, add fuel with the safc? I have emmission issues where I live and I am trying to do my homework before I sit on the dyno with the sniffer up my pipe. We basically have to pass two loaded tests; one is (i think)at 15 mph and one at 25 mph. Minimum of 1500 rpm and max of 2500 rpm.
