I have been playing around with using diodes to increase power in my 2005 Magnum 3.5 V6 and it seems to be working, yes you can buy a diode from Ebay OR you can go to radio shack and buy one for a few dollars......The trick is to use TWO diodes one goes in the intake manafold air temp sensonwiring and one goes in the ambient air temp. sensor wiring......There are no more carb choke's on cars so what the car manufacture's have done is to make cars run rich by reading what the ambient temp is and the air intake temp is it then adds more fuel and timing untill the car warms up SO if you lie to the computer it thinks it'sstill cold outside and continues to run rich producing
MORE POWER VERY COOL
