I have noticed a low power delivery(not a powerloss).
I took it to the dealer and they got back to me with the following:

Sensor is detecting lower octane gas.

I always put 93 in and the car always had normal power.
I usually put shell gas in but I think this last tank I put in gas from Chevron.
Dealer is recommending to drive few tanks full and see what happens.

Prior to this problem I had check engine light come on which turned out to be some sensor needed replacing. I don't have the name of that sensor right in front of me at the moment. The dealer said it had something to do with fumes from the gas tank not recirculating properly.

Any ideas, suggestions?

P.S. dealer seems to be very helpful at the moment.

Did ya eat chili? Mexican food? :)

Thats the purge valve I belive you are talking about.

Just drive around till this tank is empty, re-fill. If the problem does not go away after a few gallons threw the new tank then take it back and tell them to fix it.

Well, that's why you don't go right from Toxic Hell (Taco Bell) to the dealer. At least go outside before you let one rip...

I freakin' love Mexican food and chili, so does everybody else here. That's why you are a newb.

On to your issue, I think that he could be right, no harm in running a few tanks through it. But, in truth it sounds like he is stalling and hoping that with a few tanks of gas the problem will self correct. Please, keep us posted.

Was there a CEL after you had a drop in power? You noted that the dealer said "sensor" reading showed "low octane". If no CEL was present after you took it to the dealer, I'm wondering how the dealer was able to read the sensor for low octane? I'm wondering if the ECU was re-learning the fuel trims after the purge valve was replaced? That could account for a different SOTP performance.

I've used both Chevron and Shell (91) and I've found my speed6 tends to be a tad more responsive on Shell gas but that could be in my head. Please keep us updated, . . . thanks.

You know, Ive been thinking about your bad gas. I think that you should disconnect the battery and reset the computer. See if that makes any defference. There, that's an honest answer to a funny question.
