7.3 SMOKE SWITCH !!!
Did anybody ever heard or try this ? or just have any ways to make a 7.3 blow so black smoke ?
The smoke switch tricks your pcm into thinking you have full boost so it pumps in fuel. Just take your 5volt reference wire to your map and run a wire taped into that into your cap to one side of a switch. then take and splice a wire into your return (signal) wire on your map and run it to the other side of the switch in the cab. when the switch is on it will send a full 5v to your pcm and make it think you have full boost so it will dump in fuel. its really easy and it doesnt hurt anything if you do it right
