what did you have them gapped at? I'm with ducky on this one. The 'original' gap recommended for our trucks was for a platinum/iridium plug. When going to a copper plug, you typically have to close the gap down. I run around .035 on mine, and they seem to be pretty good. I'm running nitrous over boost, but should be close to the same gap (I would think)
blown transmissions are about as useful as 97% of the guys on this forum
These plugs come gapped @ .026 so I left em. I was told to run .025-.028 for boost.
wow...br's are THAT much closer then the Ts? No clue then. I wouldn't go any closer then that lol

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.
