My buddy has a 2007 Duramax and we were wanting to find out if it has high idle or if it is or could be a dealer download to enable. He really likes it on my Dodge and my truck warms up a lot faster than his does.
There is a section in the manual that talks about enabling/disabling w/ or w/o steering wheel controls
Thanks he and I will look for those things and I'll get his book from him, he's not one to look at the book if it does'nt work with big letters to spell it out when he gets it, it must not be a feature.
