For the last 10 years I've heard nothing but bad things about octane boosters.Any one has experience with octane booster?
I need to boost 87 Octane to 91 to run a BWR SC'd 05 elise. with CharlieX's Tune.
What brand of booster do i need? how much to mix?
Assume I can only get 87 octane (please dont ask why)
