If I open it up to do the chip swap, I want to know it's going to fix the problem.

You won't damage the TB if you open it, since all you're really doing is drilling off some rivets. You can always get it sealed back up to OEM specs using a rivet gun (I used screws myself). I think you should give it a shot if you can and see if that solves the problem. Won't take more than 10 mins to do the swap.

Then again, you may want to adjust the idle screw first, which is even easier to do.
