Ok well today I switch from the big tune that Nick@duramaxtuner.com makes to his Mild tow tune since I'm gonna do alot of towing. And for some reason when I start it up and if I put it right in gear or sometime when I just start it will spurted a little and throw White Smoke out? Now I've done all kinds of other tunes and it only on the Mild tow tune. I know also one time when I first got EFI Live I try one tune and then switch and it did that but I just figure it was cause I switch the tunes around. Also I noticed if I start my truck let it idle for a sec it with go from whistle to a deep tone about three times and then just whistle and no white smoke and drives fine. Any help or suggestion on this??
