The TRIFECTA Performance Buick Envision 2.5L I4 LCV powertrain calibration is an easy to install software performance recalibration with an EZ Flash cable device that will yield gains of up to +25 ft-lbs @ 3250 RPM and +16 WHP @ 3400 RPM (Peak vs peak gains of up to +13 ft-lbs and +9 WHP) to a completely stock Buick Envision 2.5 I4 (LCV).
 
Specifications of the TRIFECTA Performance Buick Envision MY2017--MY2020 2.5 I4 (LCV) ECM software reprogramming:
Gains of up to +25 ft-lbs @ 3250 RPM and +16 WHP @ 3400 RPM under the curve (and +13 ft-lbs and +9 WHP peak vs peak on 91 octane) Powertrain calibration has been tested and validated for various environments, such as cold/heat, elevation, and variations in fuel quality Power feels linear and immediately responsive (improved drivability and throttle attentiveness) Retains all GM OE diagnostics and ECM functionality Retains all OE error code reporting and functionality Emissions readiness checks are present; emissions compliant Maintains functionality of ABS and TC systems Knock detection mechanisms and OE engine knock detection sensitivity is retained With the current generation of TRIFECTA's flash loader solutions, the TRIFECTA Transparency featureset is available when flashing your vehicle.

  • 17 Digit Vehicle Identification Number.

    Must be exactly 17 digits, 9th digit must be 0--9 or 'X', and cannot contain characters 'I', 'O', or 'Q'.

    We recommend acquiring the VIN directly from the vehicle's VIN Plaque on the dash, or the certification label in the door jamb since insurance and service documents are sometimes incorrect.

  • Please contact support prior to purchasing if you have any questions: Contact Us

  • Support is not officially provided for aftermarket hardware with this calibration, however many hardware components which would normally work without any specific adjustment on the factory calibration may be automatically compatible.

    Examples include:

    -Most Exhaust components

    -Recirculated turbo bypass valves

    -Most brand name intakes (ONLY with any included resonator/venturi designed to prevent the intake from setting any DTCs (Diagnostic Trouble Codes).

    If you are not sure whether your hardware is compatible with TRIFECTA Advantage, please Contact Us for assistance!
