power loss with colder plugs?

is there any power loss when getting 1step colder plugs and gapping them to .035-.038 when not using nitrous? cause i just installed my plugs and it seems like my car is normal....?

I dynoed with Irinum (SP) plugs and had 299 HP NA about a year before I did nitrous.

I dynoed with the TR6's at 299 HP NA for a baseline just prior to testing the Nitrous.

My Big *** can't feel any difference in the Plugs.

because you pulled timing. Not because of the plugs.

FWIW this question was answered by someone who drives a mid 10 second LT1 and he replied there was no difference at all in power and he has never encountered plug fouling. I drive my LT1 with the TR6 plugs gapped at .038 and I can tell no difference from the hotter plugs gapped at .060.

Agreed. But... IMO installing less than a 100 shot is a waste of time & money. And, the two go hand-in-hand for 100+ shots. Yes, I know, I know, some guys have success without tuning their 100+ shot, but I'm a better safe than sorry guy.
