I'd bet it has more to do with elevation or the lack of that seperates the times by a few tenths...

Just an opinion though...

As far as the fuse pull concept..

why wouldn't the computer just relearn the better gas and that would be it?

bad gas....lower state of tune..

Good gas ....and the pcm reverts back to higher state of tune.

doesn't the pcm reset on anything over 8 gallons put in the gas tank?

At least thats what I had heard..

13.2 is awesome..
