Default am i just imagining a difference, switched from 91oct. to 93 oct.?

i live at altitude, 6500', and it is rare to find a station with 93. i've been running 91 since i got my '01 1.8t quattro. am i feeling a difference due to the last couple of tanks of 93, or is it my imagination? i'm not chipped.

Default Believe it Boki!

I have been using 93 with my X-chip for a month, it's much better, yesterday I had to get a few gallons of 91 to tide me over, I definitely noticed power loss with the 91 compared to the 93.

Default I live in Lubbock, Tx(only 91 cotane)

When I mixed 5 gallons of 100 octane with half a tank of 91, my car was much faster by my butt dyno.
