Hi OT,
Perhaps a very small amount if you use it (meaning 89 instead of 87) for long enough, at least several tanks, due to adaptive strategy, and only if the vehicle is run hard frequently, or is put under a heavy load as in towing, on a fairly regualr basis. But realistically, you're not going to feel anything seat of the pants, as we're really tuning that side of the dual-octane Flip Chip for an 87 octane fuel. So it doesn't have any more timing in it for the 89 octane, but under heavy load conditions for long enough & frequently enough, you might get 2-3 more horsepower, at best, from running the 89 istead of the 87 on that program. Usually you just don't notice any difference using 87 or 89 on that 87 octane program in the Flip Chip.
