my mom just bought a 2003 dodge diesel dually. i already had a 06 dodge that i bought a superchips for the 06 and on the back it says 05-06 but like if you buy them new they dont ask for the year. so will this work on my moms 03 or mess it up???

 

well since nobody said anything i tried it and it fried everything... Not really it worked just fine so i guess if anyone else was wondering that it works fine.

 

Don't joke, heard of programmers locking up ECM's and about 2-3 days straight making phone calls to get it figured out. Glad it worked for ya

not sure which one you have but i have the 3950 cortex and had it on my 04 1500 with a 4.7L and bought a 06 3500 with the cummins and it worked fine on both.
