When selecting the correct LML base tune are we required to match up only the Boot, Slave, Main, and Engine part #'s like the LML quick start guide says or is it required that we match them all up?
For instance I have a 2013 LML and the only base files that I have found on 4shared that match up to it are from a 2011 LML truck. There are no 2013 files that match up to this truck. It is a 2013 crew cab 4wd with the LTZ package.
Thanks for any help
