    missing when I start to get into boost.Sounds fine running around town,
    just when the needle hits 0# on the gauge it starts to miss. What
    could couse this? sparkplugs,wires or something else.

    probably need to shut the gap on the plugs abit. The wind coming through may be acting like someone blowing out the candles.

    Probably down to .035" for a good spark under boost.

    Well I changed the plugs and she runs 100% better now!
    There was one plug that was cracked,must have
    hit it during the header install.

    Did you use the factory gap spec or did you gap them down?
