    You're fine due to the altitude.

    K first of all, you're going to have to forgive me for this, but "whit" isn't the word you're trying to use. It's "with." The word "whit" means something entirely different.

    Otherwise 6600ft is a really high altitude so 12psi is fine as Area47 says. I'm sitting at 4000ft more or less myself so it isn't ideal. As for recalibrating your MAF, here's a helpful link I learned a lot from when I was starting out: http://www.redlineforums.com/forums/...ve-tuning.html

    Sounds like normal boost to me for the LSJ in your situation.
