The BD-Power 1057735 Throttle Sensitivity Booster increases throttle sensitivity, and reduces that laggy pedal feeling in your 2001-2005 GM 6.6L Duramax. Modern vehicles utilize an accelerator pedal position sensor to control engine fueling. Many of these vehicles respond slowly and have poor throttle sensitivity. Much of this is actually caused by the factory programming within the ECM. The BD Throttle Sensitivity Booster corrects this by making the pedal more sensitive and making the vehicle more responsive.

The Throttle Sensitivity Booster includes a wiring harness specially designed with factory style connections for a simple installation. With two modes to choose from, the Throttle Sensitivity Booster can be run on +50% and +100% modes.

  • Installs Easily With Factory Connections 
Note:The 1057735 will not work with the BD-Power shift-on-the-fly Throttle Sensitivity Switch upgrade.

A pretty big price for not a whole lot
(Denver Co) | January 8th, 2020
This device will not make your vehicle more powerful in any way shape or form. It simply makes the throttle more sensitive. ie- if you push the throttle 20% it changes it to make the vehicle think your pushing it 30-40%. The one made by pedal commander will actually change the mapping and give a more direct feel. However pedal commander doesn’t make a device for trucks older than 2008 so this is pretty much the only option. It’s fine for what it is but overpriced. It’s simple to install and works exactly how it says it does. But the change is definitely not worth the price. I would want it around the $150 mark. But if you shave everything else on your truck already, this is definitely something that will make a noticeable change. Definitely invest in a tune before this.
