    Currently I run autolite 605s pregapped at .60, picked up a set of msd coil packs for basically nuthing when I put them on i bogged out when floored. My question is I'm reading most boosted applications gap are .30 ish should I decrease mine or what are other people running?

    mds coils dont work so well all the time. put the stock coils back on, bet it runs fine again.

    unless you cross a plug wire of course.

    stock plug gap is like .055, which is huge. .030 is too small. I run mine smaller than most at like .045.

    if your stock 060 is stock, you could do 58 tho.

    i run 52 with a load of bolt ons.
