Defueling for 07 Duramax

[dtehop]

I'm looking to buy a Predator tuner but I want to make sure that it is a good fit for my truck. Currently the truck is stock but will have a k&n filter this week. Does the Predator have defueling to keep the allison transmission from slipping. I've noticed that some other programmers out there do have the defueling but their price is much higher. The predator seems like more bang for the buck.

And it is a LBZ motor.

yes, the tunes are set up to defuel between shifts.
