Here's what all I've done so far:
TB bypass
Lid
Bosch Platinums gapped at .060"
EGR mod
I'm in NORTH Georgia(any further north is NC), in the hills, and it's been hitting 85 on a hot day lately. So I doubt a hot IAT would be the culprit. I'm flat-out STUMPED.

I have seen this before, look into a cooler heat range plug and it will likely fix the problem I would try the TR5 or maybe the TR6, I understand most people use these for power adders but it works real well and if you gap them to .050" they should not cause a problem, it allowed us to make like 30 more on a car that would ping on the stock tune with 100 octane before the fix!

I just wasn't thinking when I got these plugs. Guess I'm gonna pop'em out, gap'em at .050", and pop'em back in. If I get a high-end plug next time, I'll spring for those $20-each Iridiums.
Which is colder, the TR5 or TR6?

TR6 plugs are colder. Part number 4177. Cost $1.59 each at O'Reilly's. I have them in my car gapped .045".

Like stated above, I have heard the same about the Bosch plugs.
