Why do you ask?

Tell us a story. How high is it running and are you deleted, etc...

I don’t think there is one as everything is fly-by-wire controlled by computer.

Idle speed is computer controlled.

Spec,

When I bought my truck 08, it was allready dpf deleted. It idled at 950-1000 and it was unmanageable in parking lots etc.

When I researched the cause it all came down to the sensors/probes in the exhaust.

I crawled around and found that I was missing the furthest back probe.

I bought and installed it into the harness where the connector was empty and my idle dropped to 600-625. All good.

Is your dpf removed?? This could be your problem regardless.

Computer controlled and influenced by tune - some tuners had high idles.

What is a few of the best tuners out there for the 6.4 diesel? I did not get a tuner when i bought this truck used and there is probably no way to tell which tuner was used is there?
