I can get a new one thru a friend who works at the local ford dealer cheap, and I have another friend with an IDS that can program it, but....

Is it going to erase/write over/try to update my PCM when I install and program the new FICM? Will my FICM tuner still work as long as I return the old FICM to stock before I change them out? Yes, IDS will reprogram the PCM when it programs the FICM. Here is what i would do, return your old FICM to stock, get the new FICM and have your buddy at the ford dealer program it on another truck at the dealer. Afterall its a 6.0, odds are pretty good there will be another one in there getting work done on it. It wont matter what year it it. Have him program it on another truck and remove it and install it in yours after. Then reprogram it with your FICM programer.

thats a good idea...probably should have done that.

After thinking about it and having the new ficm(which turned out to be a rebuild) in my hands, my curiousity got the best of me. I took it apart, figured out that the power side of the board is completely seperate from the electronic side. I just swapped out the dc/dc board into my old FICM and it works great. Come to find out DORAM sells just the power board by itself now. :shrug:

My truck runs even better. AFter my PCM tuner, the FICM tuner, ECM rollback, Repaired FICM, and fuel regulator upgrade, this thing runs amazing! It idles so much quieter. I can leave the truck running at the drive thru. That was impossible a few weeks ago. Its got almost too much power. Need to start saving for a clutch....I can make the current one slip on the higher power levels :D
