Opinions please. Currently running 9:1, 521c.u., B/T al heads, 57 lower and 62 upper which equals 5lbs. of boost. Thinking about trying an upper 60 tooth, which by the on-line charts equals about 7lbs of boost. Will it live on 92 pump ??? BTW, currently removing .5* per pound of boost with my map sensor, total set at 30*. Suggestions ? Thanks.
