Just had the GT dyno and a chip burnt for it. I upgraded to the switch to have 3 different setting, now setting 3 keeps the fuel pump running all the time. Postion 1 and 2 run ok to about 5000 rpms then acts like its adding to much fuel causing miss fire. I have unplug the chip and the car runs the way it always had, so that eliminates the ecm being bad. Anyone else had anything like this happen?
