custom tune

there are a few options for a tune. but you really need to know what PCM you have. the dealer might have the ability to tune, but good luck finding a compitant tech that can do it. you could get a diablo Predator, and it will allow for custom tuning. Inertia Motorsports offers tuning options. if you plan on leaving the motor stock you could look at superchips, but who drops a hemi in a vintage car to keep it stock? the other option on diablo is to look for someone local that has the CMR softwere to tune modern mopars and they can dyno tune it for you. (good luck there though as all of phoenix has one CMR tuner and custom cars are part of life here)
