Collection: 2015-2019 Chevy Silverado 3500HD Throttle Improvement

Throttle response controllers for the 2015-2019 Chevy Silverado 3500HD, both 6.0L gas and 6.6L Duramax cabs. Stocking pedal tuners from Pedal Commander and BD Diesel with multiple drive modes plus anti-theft valet settings.

Will a throttle controller void my factory powertrain warranty? No. These devices plug inline at the accelerator pedal harness, add no power or fuel changes, and leave no ECM footprint once unplugged.

Verified fitment on every listing, no guesswork at checkout.
