Description
Enhances Throttle Response. Eliminate your Sierra's sluggish throttle response with an Axial SpeedForm Series Throttle Response Controller. All modern vehicles use a drive-by-wire system that controls the throttle body electronically, similar to a dimmer switch. While innovative, this design causes an irritating delay that is most noticeable when trying to speed up to merge with fast moving traffic or when passing a slower moving car. The Axial SpeedForm Series Throttle Response Controller actually boost this signal to eliminate the delay for quicker, snappier throttle response, making it a must have for all drive-by-wire vehicles.
Five Modes. The Axial SpeedForm Series Throttle Response Controller comes with (5) preset control modes for Stock, Eco, Comfort/Sport, Sport and Race applications. Each mode can further be adjusted with nine levels of sensitivity. This allows you to select the mode that works the best for your own personal driving style and needs.
- Stock - Acceleration is set to factory defaults. Display is NO.
- ECO - Designed for fuel economy. Display is EC.
- Comfort/Sport - Balances performance and fuel economy. Display is P1.
- Sport - Improves engine response for better performance during daily commuting. Display is P2.
- Race - Maximum performance with immediate throttle response. Display is P3.
Easy Plug & Play Installation. The Axial SpeedForm Series Throttle Response Controller connects directly into the stock throttle position sensor found on the drive-by-wire gas pedal using an OEM style plug and play connector with no permanent modifications required. The Throttle Response Controller is 100% reversible and will not leave residual codes on the factory PCM making it warranty friendly.
Application. This Axial SpeedForm Series Throttle Response Controller is designed for use on all 2020-2025 GMC Sierra 2500 HD models.
