LOL, I totally missed that part of it. I guess it depends on what big boost means. I know a fair number of people pushing 800 rwhp with TR6s.

You guys need to be more specific on what "boost" and "big boost" is. It is relative for sure.

"TR7"s gapped at .025" for 3 years now on 15psi, I've tried the TR6s and I couldn't get it to run decent with them. Change my plugs once a season (7k miles)
