I was standing outside my truck today talking about different tunes when I looked and noticed very faint white smoke coming from the exhaust at idle. This is VERY faint. I could barely see it, but could see it none the less. Is this normal? Truck is running great, but this is the first time I have noticed it.

was it a little cooler? More than likely it's just normal man. As it gets colder your truck will haze white at idle more and more until the exhaust heats up.

310 tune. Exhaust was hot. Had driven for about 20min. Prior to seeing it. It was probably around 90-93 deg. Outside.

Your fine. My truck hazes a little at idle with the 275, 310, and 350 tunes. Most like due to the higher rail pressure at idle.

My truck even hazes with the 210. I think you're probably fine.
