have a 2005 f-250 6.0L. i have the latestest updated Crom. Truck starts jerking while maintaining 55 to 60 mph / approximately 1800 rpm. i have changed tune levels and even when back to origional backup tune and all have the jerking at the same speeds / rpm. i have also tried all of the croms available on the download page and cannot get rid of the jerking. I also keep throwing these codes: P0266 cylinder2 contribution / balance, and P0269 cylinder 3 contribution / balance. i clear the codes and after driving truck the same codes are thrown. the truck still had the jerking after clearing codes. i checked fuel filters and they seem fine. the truck doesnt jerk while city driving, only on the highway. if i keep rpms up above 2000 on the highway the jerking goes away until the tranny shifts.
Hopefully someone at DS can help me this time. maybe trying a new crom file or something. any help will be appreciated, it seems this jerking problem is becoming a problem for alot of people.
my calid is : VXCF0DB

IF the truck does it while stock then it needs to go to the dealer and be checked... The codes that it is throwing are not normal. You might have two bad injectors...
