IF you have an edge fueling box, you can try it. IF you dont, its not even an option. but yes, you unplug it from the motor, and the edge wiring completes the circuit, i dont know why...and you dont throw a code, because I dont know why???? and yes with stock injectors youll roll the coal, my truck doesnt hardly throw any in neutral when revved, but map sensor out it throws a HUGE cloud...AND it wont be SUPER doggy, or slow, u MIGHT notice it, u might not. Roy, if ur gonna run new big injectors, itll be sooo smokey already, so ha i wouldnt bother with this
