Supercharged spark plug question.

I already have NGK-TR6 plugs in my truck and it time to change them. Would there be any benifit for me to go to TR8 or TR9 being supercharged.

i would stick with the tr6's at 10psi. even up to 12-14psi.

they dont make a "tr7", the next stop cooler from a tr6 is a br7ef then a tr8. with the br7ef i got a noticalble miss at idle.
