that one is good, I was at the dealer and they gave me the new one. it is great but I get ~3 mpg less. So I am getting mine reflashed back to VXCF4. And my tunes go to VXCF4, that is the 2nd reason

Thanks for the help. Do you know anything about raw fuel in exhaust?

If you have fuel coming out of your exhaust then you have injection issues.

It's raw fuel in a white haze and it only does it during idle cold or warm. No other engine symptoms at all. I was getting an exhaust bp sensor code but put a eliminator on it and it went away. I also deleted the egr cooler but left the valve in the motor. I turned it off with the sct tonight and the smoking seemed to clear up. I'm not sure be suspect the pcm was giving a fuel strategy that was incorrect because it was getting some false sensor readings. Does this sound right or am I way off.

sct tunes, but it will smoke without any tunes in it. seemed to start after the egr was deleted last spring and seems to be getting worse.

Return it to stock. see if it still stinks on cold starts.

Between that and the P0611 code in your other thread Im inclined to say your Swamps FICM is bad
