Proud to own a max, although getting it has taken a big chunk out of what i had saved ($400 left!) So i won't be in the market for $mods$ any time soon. that's why i'm looking to advance the timing. suggestions on the degrees foreward? and where to get this done? i fear blowing my valves if i do it myself. cost? what octane would you use- 91 or 93? 87 would be risking predetonation, right?
