Default how cold of plugs for 10-15psi?

running TR6's right now at something like .035, going to try and push the boost on a stock 6.0 with a t76single, with 100octane i think i can get over 10psi, maybe 12 or so if i am lucky.

what plugs should i run with that in mind? with the tr6's the idle got much rougher than the stock one's, will even colder plugs be even worse?

Yep the idle will get worse with colder plugs. I have 3 range colder plugs in my LT1 and it doesn't idle well at all unless I have driven it several miles.

If you plan on running higher boost, at least go .032, and possible .028. You don't want spark plug blow out. I would suggest the NGK Iridium IK27, or the NGK Copper.

i would think how cold you can go is dependent of the static compression and it being able to idle right... once you're under boost you could go much colder if you never let off
