High idle?

[Gootee]

A buddy of mine has an 03 with 180mm rcd injectors and a 65mm powermax along with a airdog. Wether a tune is on the truck or not it always idles around 750. Never seen a 6.0 do this before and was wondering if this was common/ a problem or anything. Thanks guys

Does anyone know what sensor bumps the idle up when its cold out? Maybe a bad sensor telling the computer its cold.

That's what I told him was it probably thought it was cold all the time, but 6.0's to me are a whole other world.

I think it works off of a few parameters, one of them is oil temp, other may be air intake temp? Not sure.
