Control the throttle response in your 2007.5-2018 GM 6.6L Duramax and GM Gas Vehicles with XDP XLR8R Throttle Adjuster XD302. On most modern vehicles today the throttle pedal is "drive-by-wire". The "drive-by-wire" configuration creates a laggy pedal feeling. This throttle lag down low can make it feel like your vehicle lacks power, and can even make for less-than-ideal situations in daily driving, like pulling out into traffic. 

The XLR8R fixes this by installing in-line with your OEM wiring harness and modifying the signal going to your electronic throttle. Built for a simple installation, the XLR8R installs in no time with just a few quick connections. Included is an in-cab handheld controller that provide you with settings so you can fine-tune your throttle sensitivity with just the touch of a button. With settings from Mild to Xtreme, there's something for everyone. In addition to a throttle boost, the XLR8R can also decrease throttle response with the Valet Mode, and completely stop throttle function with the Anti-Theft setting. Once installed, you'll notice a night and day difference in throttle response!
