It's unclear that going from 91 to a higher octane will convince the ECU to yield more spark advance -- thus without planning to tune for higher octane levels, I wouldn't worry about it.
Lower octanes, however, run the risk of knock under load, and thus are not recommended. Also, in what few empirical tests I've ever found, even good octane boosters raise octane by no more than a .5 to 1.5 points. There's a thread on here somewhere with a link... Finally, depending on the additives, it may wreak havoc on the fuel sender. I say, pass. Read up on octane and its relationship to engine tuning independently -- good stuff to know about.

I use Torco it works great for eliminating da knock .

Funny to see the bashing when folks have no experience with it. I ran Torco on my race tune at over 600 rwhp as extra protection at the track. It works great and you can bump timing if desired. For me the extra octane was just for protection against detonation at 22 pounds of boost You can bump 91 octane to 105 - works great Comes in 32 oz cans - better deal is a 5 gallon can - then I used to move it over to a VP fuel race jug. ![]()
