Pedal Commander for GMC Sierra 3500HD

Installed it in my 2015 3500HD and the difference in pedal feel is immediate, especially when towing. The 4th Gen compatibility was spot-on, and the adjustability lets me dial in exactly how responsive I want it.

The throttle response is noticeably sharper now when I'm merging onto the highway with my '12 Sierra. Installation was straightforward, took about 15 minutes under the dash, and the city mode setting really helps with the sluggish factory pedal feel.

Towing my 30-foot fifth wheel up a steep grade used to mean constant pedal mashing, but now the throttle response is instant and predictable in the city mode. The install was plug-and-play on my 2015 Sierra, no tools needed beyond what I had.
