I have a chip programmer that came with my 2003 2500 5.7 gas Dodge hemi ram 5 years ago when I bought it I have never put it in and I would like better gas mileage a guy asked me how the program was and said I should buy a new one? So my question is which one should I buy for that year and engine that is affordable and works well with it? Thanks in advance for your answers

You have a tuner, most likely a Diablo (green) or Superchips (red). A newer one will not do your 2003 any good; the tunes are the same and any features that might be available on a newer tuner won't work with your truck. Keep the one you have and just use it.
