I saw the CAI in the UserCP too.
So, since you're stock, if sounds like a problem with the canned tune. I'll add, though, that an ECT reading of 230 sounds pretty high. I wonder if the CHT got above 250? If it did, then your truck was likely in "failsafe" mode (shuts off 4 cylinders to cool things down and gives you "limp home" capability).
It would be instructive to know what your CHT was. "Failsafe" is commanded at 258 degrees.
However, I don't see why a few WOT runs would heat up your engine that much.
