However, since you switched from Midwest 93 octane, to West coast 92, I'm almost wondering if there might be bad gas at the place you purchase it from.
Do this, go to your local autoparts store and get a $2 bottle of octane boost and add that at your next fill-up. See if your problem steadily goes away over the period of that tank or persists.
If the problem persists, then it's not related to the gas. If it goes away, then I'd suggest changing gas stations and/or buying Longassname's Stage 1 chip and running the 87 octane code.

clean your throttle body and check get those O2 sensors replaced or run the codes...get those fuel injectors cleaned... or fuel filter changed....im having the same problem with hesitation and the launch lol
