Also, why are you using 89 octane? This engine is made for 87 and it doesn't help to run 89 without a tune. If you have knock with 87, get a dealer tech to ride along and hear it so you don't waste your time and come out with them saying "we couldn't replicate the problem".
Actuially tried several different gas stations. As I said, I tried 87, 89, and 91 octane just to see if the noise changed. It didnt. And yes, good idea about the ride-along - I was also planning on doing that.
