シボレー・シルバラード シャシーキャブ用Pedal Commander（4500 HD/5500HD/6500HD）

Plugged it into my 2020 5500HD and the throttle response difference was immediate, even on the lowest setting. Makes hauling a loaded trailer feel much more natural around town.

I was a bit skeptical about spending the money, but the throttle response improvement on my 2020 5500HD is night and day. The "Eco" setting actually saved me a noticeable amount of fuel on my last long haul, which was a pleasant surprise.

Sport mode is the first thing I tried on my 6500HD and the throttle response is night and day compared to stock, especially when the bed’s loaded. Took maybe ten minutes to install under the dash and the LED screen is easy to scroll through even with gloves on.
