Dave,
I fired off an email to Anthony Saturday evening and he called me today.
I went over the symptoms, stutter from about 4000-4500 rpms, forgot to mention the smell, and he mentions getting the SP 534 plugs, I forgot to ask him what to gap them at, or he said to double check the gap on the stock plugs. Then he said, now I might not get this quite right so remember these may not exactly be his words, that Ford changed their electronics (ecm?) and LMS is still uncovering little things, and as fixes come out they will let us know.
Again, Im not saying what I just typed is gospel, I did a LOT of drugs back in the 70s :-)
Anyway, he told me he would send me the cold weather tune but it might be after New Years as the guy who writes the tunes is off until then. All fine and good, youre only talking 2 days, and I want to flash it back to stock to take it in and have the oil changed.
Im not changing oil when its -5 or more below zero
