I'm getting a bit of a ping when I punch the gas pedal, so I switched to a higher octane and it still pings a bit. Could it be the knock sensor? If I change it, how it affect my performance? Thanks

If the KS has been removed and replaced, I know for a fact that it's possible to overtighten and get it too sensitive.
If nothing else has changed (including fill-up source), I'd be inclined to look at the ESC as the culprit. Or, change stations to be sure. As stated, use 91 (or higher octane).
In the winter, I sometimes wonder if complaints could be related to moisture in gas.
Or the engine could be on it's last legs. We tested it with the thickest oil we could find and that was able to bring down the knock count and the oil pressure.
