    So I. Went the radioshack and bought me som watt 5% toleranceeresistors I boughtat 150 1/2 and some 100 1/2 watt I put the 150 this morning and I noticedthat the truck doesn't whistle as much and. Turbo boost. Is only at25 and takes longer to get there the 100 ohm makde a bit of a difference truck smokes a bit more during shifts. Is there a problem with this truck or does the resistor affect the valve behind the fuel filter before I did any of the resistor gig the trucks turbot
    whistled loud. And made 30 lbs.quickl y I heard about the resistor trick and I wanted to see if it would benefit my truck but looks like maybe my truck doesn't like the resistor I took it off and plugged it back in the sensor and truck is working like it used to but does anyone know why my truck wouldn't like. The resistor thank you I greatly appreciate your help

    Hmm do you thin the. Reason I dint get to see results like you was because of resistro size I took it off and. The truck runns like it used to no smoke no hard idle and truck whistles loud and makes 30 lbs of boost without hesitation does yours still whistle loud and boost is good

    I was told to use 80 ohm resistor and I could tell a big difference all the way around. That was on 475E
