2018--2020 Buick Regal GS - 3.6L - Elite

TRIFECTA presents a complete powertrain power delivery profile calibration for the Buick Regal GS (RPO: LGX) engine and corresponding 9-speed automatic transmission recalibration. The TRIFECTA Performance Buick Regal GS LGX powertrain calibration is an easy to install software performance calibration with an EZ Flash cable device (EZ Flash Cable) that will yield gains of up to +17 ft-lbs and +23 WHP (Peak gains of up to +12 ft-lbs and +22 WHP) to a completely stock Buick Regal GS LGX.
Specifications of the TRIFECTA Performance Buick Regal GS 3.6L LGX ECM software reprogramming:
Gains of up to +17 ft-lbs and +23 WHP under the curve (and +12 ft-lbs and +22 WHP 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 Return to stock functionality included with EZ Flash cable and software  
TRIFECTA Driver Selectable Vehicle Modes (DSVM):
Modify driving profiles based on the cruise control enable setting (vehicles equipped with cruise control only)
Standard Mode:  Cruise Control ON (armed) = Vehicle responds to pedal input and shift logic similar to factory programming TRIFECTA Sport Mode:  Cruise Control OFF (disarmed) = Vehicle responds more aggressively to throttle input, shifts are optimized for performance  
Specifications of the TRIFECTA Performance Buick Regal GS 9-Speed automatic transmission recalibration:
Supplementary 9-speed transmission recalibration compliments the ECM reprogramming and completes the TRIFECTA Powertrain Calibration: designed to work in unison with the ECM reprogramming for optimized performance Improved shift times in adverse shift patterns Improved shift logic (improved drivability) Does not shorten transmission life or increase cooling requirements Retains all OE diagnostics and TCM functionality Retains all OE error code reporting and functionality Improved fuel economy with improvements made to torque converter slip profiles Retains all factory drive modes: Tour, Sport, and GS.  
Installation Notes:
Estimated installation time of ~20 minutes Premium fuel is recommended for maximum power output, but not required
