I want to supercharge my 03 hemi, but I cant seem to find a kit online anywhere. Everything seems to be for an 04 and up. I saw on the Kenne Bell website that the ECM seems to be an issue on the 03. They called it "unprogrammable" for a supercharger. What are my options? What kind of problems can I expect doing an ECM swap to a newer one?

 

good luck on the ecm swap... there are threads about it but it seems more aof a major PITA than anything. i head paxton makes one for our trucks. if anything get a sts turbo kit. seems easierto install and gives a good amount of horsepower

 

I looked at the STS setup, but I'm not a fan of the remote mount being under the truck. It looks like it would be too easy to pick up dirt under there. I'll look into the paxton though. Thanks
