**2011-12 6.7L v4.0 Tuning Update**

Available tomorrow will be the v4.0 update for our 2011-12 6.7L customers. There will likely be a 2013-14 beta version available next week as we continue to make a few tweaks to the transmission tuning on our 2013 shop truck.

v4.0 changes:

Engine file corrections for trouble codes P02E1, P2074, P0402, and P026A.

Trans calibrations are all new. Note that the "Enhanced Transmission"
calibrations are now gone. We've integrated the performance benefits of
the enhanced transmission calibrations into the normal, base files and
optimized them across the board. There is now no need for separate
calibrations; all files will have enhanced lockup at wide open throttle,
with normal converter performance at part throttle.

165HP and 200HP "Quick Response" files are added. These files have
throttle dampening removed for increased pedal response and less lag.
Overall performance benefits greatly from this. Files are otherwise
identical to their matching counterparts.

You will need to contact tech support to receive the update and index file. These will be taken care of in the order they are received and the process will be the same as previous updates as far as required information goes.

If you have any tuning update specific questions, let Matt or myself know on here.
