A slow drive-by-wire pedal makes a Duramax feel late pulling into traffic. Replace that delay with the Bully Dog Thruster 49003EO, which changes how fast the pedal signal rises and does not rewrite the ECU. Order this EO part, not a non-EO Thruster.

• Build: The module plugs in line between the accelerator pedal position sensor and the ECU harness and changes the pedal ramp rate. The knob runs from 100 percent maximum increase down to 0 percent, which is the stock pedal. The end user cannot modify emission-related data files.
• Part number: Bully Dog 49003EO. CARB lists it as the Bulley Dog Thruster, manufactured by JMS and marketed by Derive Systems. It is not 49002 and not 49002EO.
• Fits: Executive Order D-784-8 covers 2008-2019 GM 2500 and 3500 Silverado and Sierra trucks with the 6.6L turbo diesel. It does not list 2020, and it does not list a 1500.
• Does not fit: Not a 2020 truck, even where a catalog name says 08-20. Not a gas engine. Not a Chevrolet or GMC 1500. Not a Ram.
• In the box: One control box, one wire harness, one on-the-fly knob, and four cable ties. No tuner.
• Emissions: CARB Executive Order D-784-8, only for 2008-2019 Silverado and Sierra 2500/3500 trucks with the 6.6L turbo diesel.
