Engine Rev's high, slow to accelerate

I thought it was normal but ive driven other Eddie Bauers w/ the 5.4 above 100 degrees and they didnt do that so im hopeful the reflashing of the PCM will bring it down to normal again.

Took mine to the dealer today for the same problem. They reprogramed the pcm with the latest and greatest codes.So I hope this works

I am a new 03 Expy EB owner and am not sure what PCM is? The car was manufactured in May(B) edition. What if anything should I have done?

Thanks for your help,
Todd

I have a 6.4 diesel and it does the same thing. Anybody know if it's the same issue?
