Cheap/easy PCM/CMR fixes and custom tunes

i got an 04 pcm from a 2500. w/ a manual trans. and i need to get a tune on it. i have a tune for a 04 ram 1500 but since the pn's are diffrent i need a new tune or have the pn's changed if i sent you the tune do you think you could change it to work with the new pcm?
