[QUOTE="kevinp, post: 10307770, member: 106826"] I didnt say anything was wrong, thats why I'm asking here if its normal practice, I'm new to the whole Ford thing. I've always tuned my own EFI cars, had pretty good luck over the last 12 years or so but the tuning options are limited on these. I'm sure there is a certain mph that they shut off (at least I hope so anyhow), but that doesnt do much in city driving. Nor does running it from a cold start, but maybe there is a limitation in the tuning software and thats the only way to do it. I have no problem with dropping the fan temps, but naturally the thermostat is going to dictate the engine temp no matter how hard you run the fans. Running the fan 100% at 196* pulling air through an ice cold radiator doesnt get a whole lot done. Its takes quite a bit of current to run the fan and you are paying through the alternator having to work harder so its not free. Like I said I dont want to start an internet tuner pissing match, just want to know if everyone does something similar, if they do its no big deal. I'm sure it will change once there is a lower temp thermostat available so its not that big of an issue, annoyance maybe, but not an issue ;) [/QUOTE]
