Mileage Flash From The Dealer
i have never updated my 04 1/2. i took delivery in june of 04 and it was ordered for me so i assume it was made shortly before i got it. i have never had the dealer update the software. i heard that the there is a flash to correct the overhead and it will help the actual millage also. question is, does this hurt performance? if it does help the mpg and does not hurt the performance will it make a diffrance once i reload the smarty?

Depending on the dealer the TSB's (associated with downloads) are normally free. With a 2004.5 truck this flash you are referring to is nothing more than an ECM update to correct the fueling %. On paper it likely effects performance but you won't feel it. If you are really worried about it get yourself a smarty box and download the best program that fits your driving style and go from there. The stock flash on the smarty contains the most up to date version of Dodge's stuff anyway so it might work better for you.
