Two weeks ago ... installed GMC performance exhaust.

Last week ... installed Range DFM disabler (RA007).

Pretty happy with both. Exhaust doesn't center on the cutout in the rear, and stealership can't do anything. So I am going to take it by an exhaust shop tomorrow to see if they can adjust. Pretty annoyed by that.

Can you share some more about the DFM Disabler? I didn't realize they were available for our trucks.

Also, do you know if it conflicts with the Autostop Eliminator? I've got that installed already.

It's pretty straight forward to install. It sits between the ECM and the connector -- that's located inside the driver's side wheel well. It disables the autostop as well, so you'd likely just use this device and get rid of the other one.

There's a discussion on this forum: https://www.tahoeyukonforum.com/threads/dfm-disabler-released.150279/

And here's the device: https://www.rangetechnology.com/products/dfm_module/parts/RA007

But also… big hit! Thought about going with some ZR2 17” wheels to avoid this type of damage but since this is not typical supposed I’ll just go with a $200 eBay pull off replacement instead. IMG_3506.jpeg

I’ve got the auto stop eliminator and also recently installed the DFM disabler. No conflicts between the two. Both products are in-line devices so no software modifications with either.

Installed a black grill from eBay. Good fit and finish similar to factory grill on RST and comes ready for front camera. Easy swap and huge improvement over the stock High Country grill. Next up is blacking out the silver lower bumper trim front & rear and then decide on some black rims.

Note that to swap your grill you will need to take off the bumper to remove the old grill and install the new one.
