Uhhh, yeah, advancing timing when your not on the proper gas is a bad thing. Just as running more than 21 lbs of boost imo on pump gas is a no no. If you do, make sure you are properly tuned and have an accurate A/F ratio ie wideband. And when I say 21lbs, I don't mean your avg 16G turbo, i'm meaning Green Territory or larger, and even then I wouldn't do it all the time. That's just my take on it, other's might disagree, but i'd rather be safer than out BIG $$$$ later.
