Collection: 2020-2026 GMC Sierra 2500HD Throttle Improvement

Throttle response controllers for the 2020-2026 GMC Sierra 2500HD eliminate factory pedal lag on the 6.6L gas and Duramax diesel. Shop Pedal Commander and other plug-and-play modules with multiple drive modes (Eco, City, Sport, Sport+) and Bluetooth tuning via app.

Will a throttle controller void my powertrain warranty? No. These modules plug into the accelerator pedal harness, do not alter ECU tuning, and can be unplugged in seconds before a dealer visit, leaving zero trace.

Verified fitment for your Sierra 2500HD, no guesswork.
