Octane booster?
edit: forgot to add, using a higher octane fuel doesn't increase your power at all just adding it to your tank. It gives you an increased advantage to run a more aggressive tune, and that is it. So if you just add it thinking you will gain power you are wrong. You need to tune for it, increase the timing and run a higher a/f within a tolerable range, etc. That is why alot of guys, like me on my turbo setup car have a race gas tune and a pump gas tune. I run the pump gas tune to have some fun on the street from time to time and a race gas tune when I am going down the strip.

Also agree with your statment about performance. With some more modern cars you may see a bit of knock and the computer will fight this by reducing timing automatically. This reduces performance. This is why you will see someone THINK that race gas increases their car's performance. It's not, it's just making it run like it is supposed to. If the knock was tuned out like it should be to begin with (for a street car) there would be no performance difference.
(The Grand Prix I talked about before had a 2.3L Whipple Supercharger on it at about 18lbs of boost...wanted to run that sucker up to 25 lbs but had intercooler issues before I could do that.)
I used to have a nearly endless supply of anything Holley (ex's mom worked in the HQ here). Her dad's TC88 wideglide had the first set of hooker pipes for that model (the ones that look like V&H BR).
I got a lot of small earl's odds & ends & a weiand intake for my LS6 nissan 240sx.
I ran nos booster with premium pump gas along with a mild EFI Live tune (on the fly tuning is awesome). The difference at 5k rpms or so was noticeable. I was always afraid to run race gas & mess with the spark too much from all the horror stories I heard about how touchy 3rd gen small block chevy's were/are.
