    These plugs come gapped @ .026 so I left em. I was told to run .025-.028 for boost.

    Lol yeah. I'm wondering if it needs the crank re-learn procedure. But there's no codes.

    I had at least one dead cylinder this morning for about 5 miles. Still no codes. Wouldn't you think there would be a random misfire code by now? Any suggestions on how to diagnose this?

    why not continue to run the tr6? if your truck ran good on them before and the only thing you changed was the plugs id guess the new plugs are the culprit.
