[QUOTE="COBB Tuning, post: 1398888, member: 30143"] There are actually no changes for the 2017 Raptor OTS maps between v103 and v104, so reverting back to a v103 will not fix the idle roughness. These map revision numbers were just increased to stay in line with other model year Raptor OTS maps that did receive changes (for v104, that was only 2018 Stage 2 91/93). I would suggest driving the truck for a few days to see if the behavior persists, and whether or not it happens under certain environmental conditions (temperature, humidity), or under certain driving conditions (cold-start, hot-start). Some roughness at idle is considered normal by the dealership/factory calibration. Also as an FYI, whenever you update the firmware of your Accessport, any new revisions of OTS maps will automatically be downloaded and made available for you to use. [/QUOTE]
