A friend of mine, with the exact same truck as I have, had a flash done on his truck against his wishes. He had no issues with the truck at all but they flashed it anyway. Now he says that there is less power (noticably) and horrible fuel mileage (he gets less than 380 miles to a tank). This is what the sticker under the hood says:

PCM (ECM) FLASH
453257553AC
RRT Send Action
#06-053-42294

I have looked everywhere and cant find any info on this. Anybody have any help for him. Before anybody says to ask the dealer, we already have...they seem to know less about these trucks than my dog. Any help is appreciated.

It was a flash. Not due to a TSB, but what is reffered to as a Rapid Response Transmittal. Here's the low down on it.

I appreciate the great information, but exactly what does it mean...and why wasnt my truck flashed(our trucks are one number off on the VINs). Could this be the cause for the low power and terrible fuel mileage? cause my truck pulls like a freight train.

They did the flash while he had it in for an oil change.

PM me your vin and I'll see. A RRT has to be done ASAP and usually because serious damage or safety concerns could happen. From what I can tell according to the "buletin" it shouldn't have affected power or mileage. It looks like all it did was change what the ECM was looking for from the rail pressure sensor.
