As for the key on/off thing, I'd generally assume you were correct about working in both positions, however there have been a few situations with the yellow and purple wires on the TB pulling loose or breaking due to the engines motion. Of course, the fact that you can reproduce it EVERY time leans against this theory.
MAF failure will put you into forced SD, but won't limp a car. I'm not running one at the moment so I can't reference my log.
Were there any major changes to your tune, or was it just an emissions/vats delete?

That I'm not sure about. I told him I had shorty headers and cai but that's it so I'm not sure if it's some kind of performance tune or not. It was done by wait4me. I called Jesse last week and he pulled my tune up and said everything looked good but since it has done this from the very first start, I'm starting to wonder is something is off. Another member here offered to look at it for me if I shipped him the PCM so if I can't come up with anything else in the next couple days, I'll probably ship it and maybe he can find something that has been overlooked.
