This is getting deep
 

:s:I hope someone can help me out. Can I do anything for better performance, fuel mileage in particular at this point in time. No delete kits , no this no that. Just got the the truck. what is fast idle override ? I need an overview by some who knows what is going on with 6.7 2008.

the wasting of fuel is the regen cycle to burn what the dpf catches. :hellox:

You will love this site it will show u exactly how to do the high idle feature

Thank You, I visited carbonite, much information given. I am starting to get the Idea now. I see there might be options yet.:tu:

there are lots of options. alot of tricks as well. a way to get around anything .

I dont know if i understand what yer tryin to do but if u want to idle up just turn the cruise on when its in park and hit set, that should idle it up and then u can go up higher if u hold the accell button.

not if the wire is not grounded to activate the the high idle. i think the newer trucks are already done. but the older ones must have that wire grounded out
