  • Improved shift quality
  • GearCommand™ enabled for full control over shifts - no more forced upshifts when using paddles at high RPM
  • Optimized shift points for better fuel economy, responsiveness, and use of full engine torque range
  • Eco mode always starts in second gear
  • Optimized shift points for DPF regeneration mode to complete in faster time and achieve better efficiency
  • Dyno cal feature allows in-gear operation up to wide open throttle without up- or down-shifting - very useful for running the vehicle on a chassis dynamometer. This is an extra file that gets included during the tuning process.

When I installed this update I was shocked how well it performed. Every statement made about what this does for your 8 speed is right on the Money. It shift smooth, doesn’t search for gears. This is by far a must update if you have the hot tube, and probably without it. I highly recommend this to anyone who does a lot of city driving and ultimately wants that “clunky” shifting to go away, this does it.
