In stock form, running 93 octane on the 2.0T over 87 octane, you should feel it have a bit more "pep". The ECU does adjust timing to accommodate the higher octane fuel. Nothing dramatic but the effect is noticeable. If you have even some moderate mods, like a better mid-pipe and catback, you will also feel a bigger difference running 93 rather than 87. That was my experience till I added more mods and began running an ECU tune (LAP3USA) to get a much bigger step in performance but running the Stage 1.5+ tune requires 92+ octane anyway. I currently run a E30 blend which the Red Sled really likes.
