Thrift,
Are you comparing new Champion plugs against new Denso's, or were the Champions in there for a few thousand miles?
Is anyone willing to get on a dyno?
Make a few base runs (not just one), then install the new plugs and make a few more dyno runs. I suggest at least 3 each and take the average. These runs would be during one session, not a week apart.

my champion plugs have abouit 1500 miles on them, but even when they were new i had a studder on hugh end. this was different than the tsb miss over 5200 rpm's. i can't help with the dyno run b/c i don't have a dyno anywhere near me. but the seat of my paints dyno sure feels better

.
thanks tommy
