I thought the same thing a while back. Got all new sensors and had Kenworth plug into her and tell me everything looks good. I'm no programmer so who am I to question them? It does run different with temp and altitude. I've definitely noticed that. My boost is actually a little less than normal in the cold. That's one thing that lead me to believe this program might be worth a damn. Dense air you'd think would require less boost.

The dealer can't see anything more than anyone else with insite.
Most of them don't even understand what insite says.
Can guess all day what the ecm is doing but without a pull just shooting into the dark
