I got the cax. file and did the reflash on my truck to enable lean cruise. After doing the reflash I noticed the spot where I was getting power for my LC-1 had lost power (getting power from under the dash next to where the factory trailer brake hook up is). After driving the truck I noticed that enabling the lean cruise leaned out everything from idle-WOT and cruising at 70mph my truck would surge a lot with a 16.5AFR. Since I really don't know enough about tuning I decided to put my old tune back on the truck and noticed that DFCO was not coming and maxing out my AFR when I let off the gas. I've been reading and can't find information on this so I was hoping if someone had ran into this they could lead me in the right direction. Thanks for the help.
