Fifth Gear a car show on BBC actually did a test of octane boosters. They found that all of the ones they tested actually caused a 2% loss of power. The tests were run on an engine on a dyno using exact measuments of gas and additives all giving the same results.

Higher octane pump gas has less power than lower octane. Don't know why the additive lowered your time though.

I have seen this a few times. For some reason these engines Don't like it [:'(] It doesn't matter if it is n/a or f/i.
"Higher octane pump gas has less power than lower octane."
Not really true. Basically, the higher the octane, the slower burn rate. This is due to closer / denser packed fuel molecules. It takes longer time for a complete burn. This is why running higher octane than needed usually makes less power. The way to make more power is to advance the timing to start the burn process sooner for the higher octane.

To put it in layman's terms, slower burning fuel makes less power. That was the point I was making which you backed me up on.
