The XDP XLR8R Throttle Adjuster XD303 gives you control of the throttle in your 2007-2018 Dodge 5.9L/6.7L Cummins, 2014-2018 Ram & Jeep 3.0L EcoDiesel, and 2008-2018 Chrysler Gas Vehicles. The throttle pedal on your vehicle is "drive-by-wire" and in many cases provides subpar throttle response. This laggy pedal can make it feel like your vehicle has no power on the bottom end. Not only is the drivability an issue, it can also make for dangerous situations in daily driving like pulling out into traffic. 

The XLR8R is the solution! Designed for a simple installation, the XLR8R plugs into OEM connections and modifies the signal going to your electronic throttle. With no modifications required, you can plug the XLR8R in to your factory wiring harness and drastically increase throttle response in your vehicle. XDP's XD303 includes a handheld controller that gives you full control so you can pick your setting from Mild to Xtreme. In addition to a throttle sensitivity increase, the XLR8R also has a Valet Mode to decrease throttle response, and an Anti-Theft setting to stops throttle function completely. With the XDP XLR8R, you'll notice a huge increase in overall drivability and throttle response.

I have had this product on my truck for about 2 days now. It works just as said! Valet mode defiantly CUTS THE POWER. All levels have a noticeable difference. Level 4 really helped me get the truck spooled up a bit faster when trying to jump on roadways. I am running a non VGT turbo and it really makes a difference in the low end. It does not give you any power so don't expect that but defiantly gets the truck up and moving a bit faster. Also the anti theft mode is pretty cool!
