I know that this is a dumb question to many of you but I would like to know what has been done and why? I bought a 2005 model recently and took it into a local dealer for a reflash of the engine computer. It was done as a recall. They left no stickers that I have noticed and didn't give me any paperwork but they did wash the car for free. I had noticed that the tail pipes were black with carbon inside the tips. I also know that the racing beat reflash corrects overrich mixture at high rpm that I believe is to protect the cat. So the big questions are; what did this reflash do? what rpm does the mixture turn rich?

well the newest flash is for loss of power/rough idle.....i know at one point a flash was to inject more oil

Adds more oil and makes it a little leaner in the upper range plus a slight tweak in timing.
