White is usually coolant. Grey- Fuel. You can always try to clean MAF and toss that K&N and see if there's any changes.

I have the same problem, but mine is when the truck idles for about 20 minutes. Its just a puff of whiteish smoke and than its gone.

I know GM put out an ecm update that had to do with the EGR. My truck smoked white and I didn't believe the mechanic but he reflashed my ecm. I took my truck out and bagged the hell out of it for an afternoon and there's been no white smoke since. Strange? Yes.
