    Gains in adjusting PCU on stock 260?

    Just wondered if there would be any performance gain, in adjusting the stock 260 brucato PCU curve?
    The powerheads' got minor chest work and top pinned pistons from John Marles.
    Seem to be running a little rich in general.

    Thanks
    Chris

    You will definately get gains from going slow and adjusting the fuel curve. Best wishes, Carter

    what he said. make sure your getting good EGT readings and fine tune your ENTIRE rpm range. Helps with a stem wheel so you can control while driving and go into box after you record it.
