I use 93 octane plus 108 booster with a vampire individual cylinder knock control unit, and if I am going to be really twisting her I will add 107 turbo blue. Now I cannot deny using 116 octane on days I might want to go insane
I only use tune boy to make changes in the timing except for the monitoring the Vampire unit does. Its individual cylinder control so if the somar senor hers a detonation event it retard that cylinder 10 degrees until the event has stopped them it advances it back 2 degrees per 20 rotations of the crankshaft until its back to the preset timing.
