Default Supercharged 4.6 idle

Just curious on what your car idles at with an aftermarket s/c setup, I have my idle set at about 1100, seems anything under that i have a problem with the car stalling at an idle.

im at a total loss then, thougt it was an issue with the tune, had it retuned, same problem, anything under 1k idle after a few seconds it will stall and all i smell is fuel, assumed it was spark cut too, went over the entire electrical system and nothing..... guess ill have to settle for the idle

if i were you i wouldnt settle for the idle....sounds like somethings not right and you should try to find out what it is before it causes major problems, unless without a doubt you know thats the way it supposed to run...just my opinion

mine is at about 1100 during the day, at night once it cools down it idles a little lower, but I believe with mine its because of the cams that were used, they seem to be pretty agressive.

Mine idles at 700-800rpm after warming up. Don't settle. Your car should idle like everyone else's if all is in order and tuned properly.
