I replaced the plugs, ran some techron through the gas, put in different gas, dumped the codes and checked ignition and engine timing, checked the intake system for vacum leaks, etc...

Timing was dead on. No fault codes. Plugs didn't seem too bad.

All back to normal now. It still doesn't feel as fast as it should though...

Hmm. Full boost and no pinging. Guess I'm happy for now...
