Express/Savana Van Delete Tuner with AutoCal

Express/Savana Delete Tuner

Please note that these are Express/Savana Duramax delete tune files with an EFILive AutoCal V3. This tune requires a stock read. Already have an Autocal V3? Tunes can be found here.

These tunes will turn off and allow the EGR and DPF emission systems to be removed.

These tune files are custom written for your truck allowing safe and efficient power. With custom tuning you have the option to select a power level or leave the power level stock with emissions removed. Custom tuning can also be modified for performance modifications such as larger turbos.

Multistage custom tuning allows you to select the best power level for your application. For example, a tow tune will provide a wider torque curve to assist with a heavy load. By having selectable tuning, you can maximize your fuel efficiency or power where needed or for fun.

Transmission tuning, where applicable, is recommended to increase the transmission’s ability to handle more power by increasing line pressure and moving shift points.

Why delete your truck?

The DPF, EGR, and SCR systems on your 2007+ truck are complex, prone to depreciating and loosing efficiency, or outright failing and costing money to replace.

Many a modern day diesel driver has experience of a truck in reduced engine power, limp mode or not starting because of issues with the emissions systems on their truck.

A custom tune will allow the DPF filter to be removed, and turn off the EGR and SCR systems, allowing them to be removed and bringing back reliability to your truck.

Diesel and performance enthusiasts will grin with the power gains possible through tuning, and appreciate the ability of a skilled tuner writer to properly configure other aftermarket modifications like bigger turbos, injectors, built transmissions, higher capacity fuel pumps, cold air intakes and exhausts.

Transmission tuning available for LWN and LML Duramax’s

*The E98 ECM in the Colorado/Canyon/Equinox/Terrain/Gen 2 Cruze can be difficult to get the dash messages to clear. In most cases we can get these to clear with a reset tune and other strategies we have come up with. If you do have messages present before tuning we can’t guarantee that we can get them to clear but in most cases we can. Sometimes it takes returning to stock, clearing messages, then tuning.
