turbo 5.3 plugs? this is my current setup, Front mount Master Power T70/.96AR turbo, Pullout 5.3L LM7 8.5:1 compression, 317 heads, 02 ZO6 Cam running 10psi on daily driving and 17psi when play time comes around. I have Tr6's in it now but was woundering if it would be better running a 7 heat range plug. I like ngk's so would like to stick with them if i can. Any help would be nice, thanks.
