For the record...
I'm also one who had the reflash done, as I documented earlier. Cedric wrote on my invoice something to the order of "Customer found car is running rich, check for updates to ECU." I remember that it was this way, because I was joking w/ Cedric that he spelled rich "ritch", so it stuck in my head. At any rate, he said that initally, he was unable to find a report of an update for my car, but when he looked it up, there was one available. That was all I needed to hear, because Cedric explained to me that it should help with the problem. No more was talked about it (like you guys are elaborating to the Nth degree on here), and the car now gets far better gas mileage, far less soot around the exhaust, and ZERO soot and dirt on the back hatch area, as was common when before the flash.
I also remember that the car would create a hell of a smoke-screen behind me during full-throttle WFO acceleration runs, especially when doing it from a relatively low RPM in a higher gear. Now, I see more of a steamy, soft haze as I do the same WFO run.
No more information for me was necessary, Cedric dutifully tackled this issue, while changing my oil for me, and the car's run better ever since.
To those of you who are saying that this isn't true, that there is no reflash available, I don't know what to say other then I doubt your service center's ability to research for the correct information. When I was a Service Writer, when there was an issue like this that came up, I'd research quite a while before saying "no", but others in my crew would simply go "nope, can't do it", without finding out. So, it depends on who you deal with.
