Being that my 15 Bighorn is on the list for the tone wheel issue and I couldn't have the W58 added to my current ECM I am placing my GDE ECM up for sale.

GDE Pre EPA Hot Tune
Gear 3.55


Regen Message: Yes
Turbo Braking: Yes

Asking $650.00 US shipping of your choice.

All the pins are straight and the ECM was working well when removed.

You will need to change the Vin and Injector codes with Alpha OBD.
