Try 1-800-86-MOPAR and ask to speak to Jim Perry. He is very nice and knows his stuff, please be kind.
. I had the same concern and he told me my SI PCM should be ok and so far so good! In fact since installing the SI my fan actually comes on when I let it idle and cycle, never did it before so I think my stock pcm was bad. Have the part number and the date code that is on the PCM available or he may not be able to help!
