Does it idle same/worse/better without your F6?
Do you have a high idle tune....how does this operate cold vs warm?
Compare ICP/PW on AE during the cold/smooth idle against the hot/erratic idle. Talk to your tuner. He may be able to tweak a parameter that will fit your truck, if you conclude that nothing is wrong with your truck.
