    TRIFECTA: 2021 Sierra Denali w/ Whipple SC

      TRIFECTA:  The same customer of ours that had us tune his 2017 Sierra Denali with a Whipple supercharger recently stepped up to a new 2021 Sierra Denali!

    After getting past what proved to be one of the biggest challenges we ever faced - figuring out how to get into the E90 ECM in this truck, we delivered a comprehensive calibration for the new 3.0L Whipple supercharger.

    Complete with TRIFECTA’s exclusive 10sp automatic transmission shift recalibration support (for the new T93 controller), this truck is a force to be reckoned with on the street.  We found 555 horsepower at the tire on the dyno, and 534 foot pounds of torque!

    Complete mod list consists of the SC kit from Whipple, IAT relocation module from DashLogic, a cat-back exhaust system, and our calibration.

    A big shoutout to:

    CarbConn in Kirkland, WA for the install, support, and dyno.
    DashLogic for providing the “IAT Sensor Breakout” module (SensorTap) that’s required to relocate the IAT sensor to the intake manifold on these E90 applications.
    And finally, the customer for his confidence and patience while we worked through the challenges of this project!
