Any resolution on this? I have 2 customers, one with a 99 and one with an 01 and both have this problem on the 85 HP tune. One of the P06xx codes was only applicable to california equipped trucks and they wont run when cold. Both of these are Federal emissions trucks.

Is there a list of vehicles with model years and engine that can be tuned with the black CMR chip. I was looking for this so I can put this info on my website so when a customer clicks on my Diablo tab, they can see if their vehicle is supported.
