What are you thinking that it is supposed to do?
Raising the octane in gasoline does not effect the BTU (power output) of gasoline. It only lets a motor tuned for the higher octane not blow up.
So if you are asking if using any octane boosters give you any more power, then no... it doesn't. It's some dumb tuner old wives tale that people think it makes more power.
Now if you advance the ignition timing, or increase compression (to get more power) to the point when the engine has pre-igniting or is detonating, then an octane booster will help you not blow up your motor.

It's a waste. And a lot of them don't even raise the octane, they just clean the combustion chamber of carbon build-up to bring the compression ratio back to stock.

Either way if you use a gasoline that doesn't have enough octane in it, the knock sensor will retard the timing and engine power slightly to compensate. However if you use lower than 86 octane; the PCM with the knock sensor may not be able to retard the timing enough to compensate for that too low of a grade of octane.

There's no way it's cheaper to use.....
Don't mis-read the labels - they claim a bottle added to ten gallons will raise the rating by two 'octane points' - they don't explain an octane point is POINT ONE of an octane 'rating'! So your 89 octane becomes 89.2!
You'd go broke trying to duplicate premium gas.

yeah but i figured it was a quick fix for a little. i mean it's not like i still do it. ever. honestly i felt like i was betraying my car by pouring that **** in there. and then filling her up with regular. i hated it. but i went to about ten gas stations before giving up.
this weekend I'm going to use a booster too what is a good one?

I spent a couple of days looking octane boosters up and found several independant test results showing that most dont do what they claim and the ones that do what they claim are still a waste of money.
The big problem is that the chemical many use to raise the octane rating is raising it but it causes the combustion to run hotter so you are effectivly doing nothing or in many cases making the situation worse.
Also, the knock sensor on the RX8 is basicly worthless, so nobody should be trusting it to save your motor.
If you can't find anything but regular unleaded then I you should not run WOT. plus/middle grade usually works fine on our cars as long as you have not tunned it to run leaner (AP or racing beat tune) I hear the RB tune is the most aggressive on the timing, so be very carefull running anything but supreme.
Back to the octane boosters, some are effective at raising the octane rating but I would not trust it and its too expensive.

If you google octane booster you will find tons of threads on how to make it yourself in more potent quantities. But I don't know if I would trust it. Like Highway8 said, it may burn hotter in the combustion chamber which could cause some major issues.
