Fitting your GMC Sierra with 2014-2018 throttle enhancement devices from leading manufacturers like JMS makes an immediate difference in how your pickup runs and feels – a refreshing change from the pedal lag and halfhearted acceleration caused by drive-by-wire technology. Plugging right into the truck’s electronic system without the need for splicing, cutting, or modification, these handy 2007-2013 throttle enhancements make the ECU much more sensitive to your control inputs. That means when you step on the gas the truck will instantly and strongly accelerate, while the vehicle gains low range and mid range horsepower and torque at the same time. Some of these devices come with a remote control knob, too, letting you adjust responsiveness between 0% and 100%, so that you can get your machine running exactly how you prefer.
