Did not hear any knocking event or any type of other engine noise that would call my attention.
What I am suspecting: bad fuel quality (filled with 93 from Kroeger this time)
Question: How do I diagnose if this is related to the fuel? Any other had similar reduction of power/torque?

I have had this happen on my 13' multiple times since you can't pump your own gas in OR, they put 87 in. You can see it if you have a way to look at your IAM in real time, I use my OFT to check, usually drops IAM down to .4ish, so only giving you 40%(all other factors removed) of your base timing. Seriously feels like you are down 20+whp, throttle response sluggish.
