    Ive read high and low on what resistor to use and what wires to put it in without a strait answer. Seems like nobody is really sure of what actually works. Have tried the 450ohm between the white with the sensor end white wire soldered to the black wire and the othed end of the resistor soldered to the white and black with the orange wire cut witout any noticable change. Does anyone else have any ideas?? Thanks in advance

    once fuel warms up mod loses it effectiveness if I'm not mistaken .. at best it's only a minor power gain iirc. PS don't cut your harness get a seperate plug that you modify and can unhook if needed

    Its about a 25-35 hp gain IF you can keep your fuel on the cool side.
