Pedal Commander is a company that offers a throttle response controller for various car and truck models. This device allows drivers to customize the responsiveness of their accelerator pedal, potentially creating a quicker perceived acceleration without increasing horsepower.
When you accelerate, and it’s lagging, it means there is a delay or sluggish response in the vehicle’s acceleration despite pressing the accelerator pedal. In other words, the engine’s power delivery is not instant, and there is a noticeable delay in the increase of vehicle speed.
