ok I know this may sound funny but I have a 03 dakota 4.7 and I just put PP in my truck. I noticed now it kicks down easier when I press the gas. but I think mine is my superchip programmer on 91 setting that is casuing that. I wouldnt worrry about it. I would rather it shift easier liek that. than to press the gas and it bog down and not want to shift.
try reseting the PCM and clear everything. then see how it does.
