2003 6.0 rough cold start after 9r10 update

[smorrisii]

I have a 2003 6.0 CC DRW FX4 and recently updated to the 9r10 in my U7165. I am having a rough cold start no matter what hp tune I install, return to stock , starts like a dream. My calid is VXAP2N2. Im looking more for fuel mileage, the heaviest thing I tow is a 6000 lb boat. thanks for any help..

Looks like i need to find out whats going on with the 03's. Seems to be hit or miss with this issue guys are running into. Do these problems start immediately after installing the tune? or down the road after running it for awhile?
