Ruff Idle on Cold Mornings

I'm having a problem with the engine loping at idle after a long run say about 100 miles or so. Not to bad. Going from 590- 675 rpm. In the morning when it's cold it rumps untill I put it on high idle for a minute then it stops. If I bring it to 3250 rpms it all of a sudden it tachs out to 4100 rpms. All this on the 125 hp and 150 hp tune (canned or custom). Any ideas on what going on hear. I have data logs with SCT Live Link if anybody wants to look at them.

post them. but I bet the timing is advanced too much with those high horsepower tuner and the truck's having a hard time figuring it out while it's cold. Going back to stock is the first thing you're gonna wanna do.

When I say cold I mean 70-40. What about when I rev it to 3200 and it shoots to 4150 rpms when it's at operating temps?

I tried to post them but it says "Invalid File".
