I've read good things about what swamps has over on FTE. He also has some 54v as well i believe.
Also, have your friend check for the heat inductive flash. From my understanding, Ford attempted to bandaid some other problems with an updated flash and in turn fried a lot of FICM's.
Did he do the voltage test on the FICM, I resoldered mine and have good results. I pulled a P0611 a few times, resoldered and tested and am in good shape so far.
