The leading plugs are hotter. 7 heat range in the leading vs. 9 in the trailing

I've run all 7's in some of my N/A DD's before.....never been a problem.

No ill effects. It actually runs a whole lot better that way.
Are you running all leadings? or all trailings? Never tried all 7's in a boosted (even stock boosted) 13B before....interesting.
