Ok going to get my car tuned again.

last tune i ran out of fuel at 5k rpms at 9psi and 600 hp
was running meth and 93 pump with spark plugs tr6

new fuel pumps in taking her up 6800 rpms this tune. stay with same spark plugs ? Still going to run same amount of meth but is it worth added some C10 in a 50/50 mix or 100 C12

i would try to leave the race gas out so you dont have to worry about that
unless you dont care and just want the most power possible

We use the NGK TR6 4177 spark plugs in your boost range, which are probably the plugs you have. Bob

Race fuel never hurts for safety, that is how Dave is on his second year at 825++whp with his 05' GTO on a stock LQ9.

15psi on 93 octane and I run TR6's gapped at .25 with no problems...

I just swapped to a NGK 7 heat range non protruding tip plug at 15psi and really like it. It comes pre gapped at .028 which is nice. Much better than having to squish down a normal plug gap. Don't remember the number off the top of my head tough, nappa carried them.

If you are interested I can find the number for you.

I actually burned a grounding strap off of a tr6 with 16psi.......put in a set of TR8's but they interfered with my radio and bcm......so I got the 7's and they have been working great
