How much nitrous are you spraying?
The TR55 is a stock heat range, with a 0.050" gap. That is probably acceptable for less than a 100-shot. Anything over that really needs a colder plug, and a smaller gap. The TR6 is one step colder, ok for maybe 150-175HP. The Autolite 104 is similar and works well. For anything bigger than that, you may want to go to a plug 2 steps colder than stock, like the Autlite 103.
