I've flashed the SDAutoTune tune into my PCM and the truck won't continue to run at idle without applying pressure to the gas pedal. Do I need to bump up the values in a table other than the VE table? It seems that the problem is related to colder temps. I don't remember having the problem in warmer weather.

You might need to tune your idle air flow. the MAF might have been patching up the problem. There is some info and pids etc on here.

Do a search for "idle transition" tuning.

In addition to ringram comments, what AFR is your WB reporting at idle? LSx's don't like to idle under extreme rich conditions.
