Just wondering if anyone has any experience with the GearboxZ programmer.
Did you have to put in the vin to start I bought a DPF-R 4.0 not sure if it deletes the egr and DPFThe DPF-R by GearboxZ works as advertised. It turns off the Regen and EGR function and nothing else. They do have a + tune which is supposed to add some fuel mileage too. No experience with that however.
