Shift on the Fly is offered in this package. You can change your horse power level using your trucks steering wheel controls.

By deleting the factory emission system which has been suffocating your diesel, you’ll immediately notice a night and day difference. It will perform better in every imaginable way, including speed, fuel economy (5 mpg increase on average), and fewer trips to the autobody shop.

Over time, the delete tunes pays for itself with the fuel savings alone. That’s not even considering how many costly trips to the dealer you’ll be saving yourself.

The last benefit is peace of mind, knowing your truck no longer has a ticking time bomb attached to it.
