Sorry, willdikem66, it looks like the tuner will not work for a 2003 HEMI. They skipped that engine for 2003, according to the SCT website.

To verify for 100% certainty, please contact hemifever@aol.com (Sean is his name) and see if he can tune for your year/engine. I'd love to take your money, but I don't want to screw you over.

 

hold on to that thing for me, got a 96 ram 5.2 needin a tune and an 06 5.7 which would love a tune from sean. pm me and ill take it off your hands

 

PM sent. Just FYI... you cannot use it on both vehicles at the same time, and you can't really flip it back and forth between them, either.

 

Thanks for letting me know!

 

How much does it cost to retune these to work on a different engine?

 

Please read the second sentence in the very first post.

PM sent.

 

Bump. Lots of interest, but no takers yet. Still for sale.
