Seems like Im at the boarder line(ready for a tune up)

[spadepro22]

Ill start off by saying Ive been reseaching and googling for about 2hrs now on the right spark plung. It seems Im at the boarder of the 6's and maybe not ready for 7's. Im running 17psi with small 16g(check profile for all modds). I need to tune up asap so if I have to go with the 7's Ill have to order, so the sooner I figure this out the better. (ps I need a answer, the links you will post I've probably already read) Thanks alot guys
