Originally posted by Star Turbo Talon I am not good explaining some things and that is one...but i can draw one hell of a crappy diagram..lol Impedance is the ohm measurement basically. I would install 13-15ohm 10watt or larger resistors. I say 10w because some guys here used 10watt for the resistor pack when running low impedance injectors on our circuit and had no problems. I have no idea what the factory gst pack is. If you get too low of a resistor it will burn out. i would say look for 20w if they are made just for security. they will need a heatsink and you will have to monitor the heat temp for the first month to be safe. When i build mine thats the route i am going. Hopefully i will have my kit ordered by mid next month. Keep me posted if you get around to this before i do, if not i will do the same.

I can test the resistor trick this week. Just so you know... when I used the resistors for 450CC DSM injectors to work I used 2 x 20 Ohm 25 Watt resistors on each injector driver. This works out to 10 Ohm 50 Watts per injector driver. So that's about what you need to be safe. I would say at least 25W...
Do the math... Watts = Amps x Volts We know Volts = 13.4 And the Amps are about 2 I think for high impedenc injectors. So Watts = 13.4 x 2 = 26.8W
