spark plug problems Hey guys just wondering if there is an expert plug guy on here? The problem I am having is........ I am running a TR6 plug at 31 thousands gap. I am having problems with some plugs fouling out and a couple other eroding away. 
I am running 18 psi. Is this too much boost for this plug? I am also getting random misfire codes. Obviously because of plug problems. Want to get this fixed before I mess something up. My car was tuned at GMR Speed. I have left boost alone. Just wondering what you all think.

Yes I would step down to a colder plug. The misfire will get fixed once the plugs stop getting chewed up. Either NGK BP7ES (I think thats the number) or get the equivalent Autolite. Once installed, do a boost pull, shut down immediately without coasting too much as it'll wash out the plug readings, and read the plugs timing, fueling, etc... If you want to email pics for me to help you out, cat3n4@gmail.com
Could be getting KR as well, which is why I'd like to see some hi-def pics of the plugs.
