I would like to hear from 03 hemi owners only because supposedly the 03 hemi superchips is not as good as the newer flashpaqs. If you have that superchips on your 03 have you noticed anything that would make it worth buying? Did your MPG go up when you were on performance or economy setting? Did you see a good increase in power?

 

Its worth buying for the 03's, we kinda got screwed with the change in 04. Its pretty much all we get unless you go custom. Mine has paid for itself just in DTC reading. I have yet to get a trouble code, but my wife's Liberty gets them all the time for the gas cap. It will talk to her computer and reset them. Plus you can up the top end and revs, and adjust for tire diameter. Doesn't feel like it messes with the shift points though. From what I've heard, its better than the Hypertech for that year.
