Has / does anyone use this octane booster? I was watching a Palm Beach Dyno video on UToob where they had a ST on a dyno and show the HP and TQ with stock, then PBD 93 tune, then the same tune with this octane booster added. The dyno charts indicated it made a pretty reasonable increase on HP and TQ with the octane booster. Is this stuff harmful to the engine? I wouldn't think so but I've never used a booster before so I claim ignorance on this (any many, many other) topic.. ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
