I'm helping a buddy out he bought 165lb Impedance inj on his kb 3.2 lc, slot maf , e85 , 03 cobra, tuner claims those inj will not work on a ford ecu that it's for a stand alone type pcm, tuner makes adj it's rich one tune then lean the other ? I'm asking to see if the 165lb high Impedance have worked on any ones car ? If so who did the tuning ? Thanks
