Ive read a few threads refering to mods on the hemis. I have an 04 rc, sb hemi. All i have done so far is put on a gibson super truck cat back sytem. Is it worth it for me to do anything else to it, or is my computer just going to nullify it soon after i put it on?

 

the Hemi comes from the factory pretty well tuned. it wont benefit much from upgrades like the 4.7 and 3.7, DC already did a good job of it, only other thing id do (unless you have the money for a supercharger) is just buy a chip for it. program it, another easy 20hp.

 

I DON'T THINK THE COMPUTER NULLS ANYTHING. IH IT DOES A CHIP OR COMPUTER UPGRADE MIGHT HELP THAT AS WELL AS ADD SOME MORE POWER.
