I've got the ever-widening gap problem too, had to undo some things (hate that!) and got it back on stands now. What's that saying, 90% done and 90% to go? I'm at the 95 percentile...
Talked with the MP tech line, he said to use the alternator hookup on the engine harness, the pcm will provide alternator regulation. He also said the pcm is open loop (no O2 sensors) so it'll run a touch rich (fine considering I have headers). He said they may not get the best economy. Duelich (sp?) dynoed one last year in Hot Rod magazine, I need to dig it up and see what A/F ratios they found, it seemed reasonable IIRC.
Love the tape despenser, mine is still holding the paper towell roll proudly!
