Default Spark Blow Out?

Just trying to get some input on what may have happened. First time using nitrous on this car, but not my first time using nitrous. I am running 100 shot on my car, via single wet fogger nozzle. stock timing with 112 octane fuel. my other mods are in my sig. I sprayed from a second gear roll and everything seemed fine, shifted into third and everything seemed okay, then when it got to 4000 appx, it started spittin and sputtering bad. i immediately i let out of it. i pulled over and checked the noids and bottle pressure and everything was cool. so i tried again from a 60 roll in third and it did the same thing. i am a lazy bastard sometimes, that being said, i know the pass side is a bitch so i didnt change my plugs. it has the tr55's running a .050 gap. is there a chance i could have been, lack of better terminology, blowing out the spark? i have had this happen on turbo cars in upper rpm under boost, but never on a nitrous app. it still runs great on motor, so i know i didnt hurt anything. let me know what you think.

TR6's with a .035 gap is what I'd run. Try it and let me know how that works.

yes you need tr6's gapped at .038. Thats what hsw told me to use for a 75-100 shot.

the br7's will be a better option if you plan on spraying 125+. gap around .030-.035. Some even run them at .028, but I would run as wide gap as possible.
