Occasionally a trucker will put regular in the high test tank. I would guess that undetected, it would take quite a while for the octane in that tank to get back to where it should be. I live in Ohio, which is known as a dumping ground for bad gas. What's more, many of the Cleveland gas stations are owned by an ethnic group not known for their honesty in business matters. Gasoline has a relatively poor shelf life, and some of the compounds that contribute to octane, such as toluene or other aromatics can boil out pretty quickly. I stick with Marathon, Sunoco, or Shell for my cars that require high test.

Unfortunately we have some of the worst gas in Arizona. This had been told to me over and over at various dyno shops over the years, and verified by how my Mustangs ran with different 91 octane gas. Chevron seems to be one of the better ones out there, but you may want to do a dyno run and have the A/F checked to see if you are running lean. Forced induction and detonation do not mix.
BTW did you have the dealer install your stage 1 kit? if so who did the work. I just picked up a used 08 SS and would like a bit more power.

For the people in Arizona, if it matters......
GM Desert Proving Ground (formerly in Mesa, now in Yuma) did an extensive fuel test that I was involved in.
After testing a number of different fuels and different grades, they elected to use Chevron for their fleet vehicles and emissions testing. I purchased large quantities FROM them for our on site fuel station.
Disclaimer...... Can't tell you what they are using now. But may be able to find out this coming Tuesday....when I'll be attending a GM breakfast meet.
2nd disclaimer....I don't necessarily use Chevron. Mostly whatever is handy and a name brand other than Atlantic Richfield (AM-PM).

I wish we had 92 or 93 oct like we used to have. so far ever since i've been running the Cheveron 91 oct, I haven't had one pinging issue. I will though, be sure to get 2 gals of 104 oct before heading to the track.
I've also noticed a huge difference in performance since the switch. It pulls hards and sometimes I lose traction doing a rolling run in second gear. i ordered my K&N filter and should be in today. Still have to install the down puipe. Fraking lazy guy I can be :)

Add a gallon of pure Toluene (like from Ace hardware) to half a tank of premium. If your pinging goes away, then it is octane related, if not you have something else going on and need to get it resolved.

Pinging went away when I stated using Chevron 91. I was using Shell and QT before. So far no pinging issues

Sounds like it is the Techron additive that is helping your pinging issue
