Getting rid of the side effects of drive-by-wire in your Sierra pickup, using 2014-2018 throttle enhancement components, makes driving your truck a lot more enjoyable and has some practical benefits, too. These plug-and-play parts, from companies like JLT, are designed to greatly increase the responsiveness of your truck’s electronic control unit (ECU) to throttle inputs. The throttle enhancement straight up frees you from pedal lag and turbo lag, and is often stackable with other programmers, too. You can also count on fast, strong acceleration and a notable gain in torque and horsepower. These enhancements include variants that are supplied with remote controls, so that you can dial in whatever level of throttle response you want at any given moment. These parts are a great way to get a stronger, quicker, more responsive Sierra pickup without making any major modifications to its engine or systems.
