Flash PCM with new software better MPG?

Searching around on ebay came across this 2004 ford Ranger.

"I recently had the PCM (computer) flashed and updated at Ford on a WDS with the newest program for better gas mileage."
Is that even possible if so why don't they talk about it to encourage people to do it.

Thats a very good question. If you find its possible let me know! I changed plug wires to taylor thunder sport 8.2 mm and that adds lots of power. Suprising i know but also good for gas.

I have heard of it before.

They had a recall on some trucks with the 4.0 i think which updated it to a new version. That was around 04 models.

Are you talking about the TSB recall when they set the calibration code lower in the tranny?
