    Has anyone used the FIE single stage lean out while on the two step. I'm running a converter and the egt temps decrease greatly on the two step. If so what was the result, what jet did you start with, any info would be great.
    Thanks ITA

    Haven't used the FIE Leanout but as far as the jet depends on if you have a Roots blower or a screw blower and how much boost you are making on the Two Step. Knowing this and what the current GPM is on the Two Step helps select the current jet.

    This is going to be used on a roots car. Making around 32lbs while on the two step. Currently I do not have a flow meter, so no GPM data. If someone has one for sale lets talk.
    Thanks ITA.

    Since no flow meter I would start with a .060" jet and increase to .080" and .020" at a time until you get close then by .010" until you are right on.
