Mine has 30 miles on it. It idles a bit rough when cold. I think its a lean condition....Maybe the fuel map is lean by design??

Cold engines should run on the rich side until warm. They are running a open loop map until a set temp. is reached then they go closed loop and run off of the O2 sensors.

I have noticed mine a bit rough a few times. I dont idle the truck much so ive not been able to pay too much attention to it.

Figure it is time to update this thread with my fix. I actually started to get multiple misfires with mine at the end. So I fixed it all by having the motor and trans swapped for a 5.7 hemi and truck 8 speed transmission. No more rough idle or misfires.
Hopefully those that are experiencing these issues at some time get a fix for it.
