Octance booster wont do crap...it goes by "points"...almost like on wall street going by basis points. It's not really "1" point added to the 93. More like...1/10 or 1/100 of a real point.RZJZA80 said:Where does everyone get race gas from? I'm down in Houston. Can adding octane booster (1 or 2 bottles) be sufficient?
