Help 6.7l Loping at idle

[jonathanrayce]

Can anyone tell me what may be happening to this truck? When idling cold it has a sort of a lope to it. Any help will be greatly appreciated.

Post the tune file...its hard to extrapolate from a log.

What are the mods to the truck??

Turning on the exhaust brake makes a difference in the loping while idling if that helps.

i just got done taking a look at your tune, looks like when you smoothed the piolet injection it added too much to the idle area. i put them back stock and turned off the post injection see if this fixes your issue.
