2017--Present Buick LaCrosse - 3.6L - Advantage

TRIFECTA presents a complete powertrain power delivery profile calibration for the Buick LaCrosse (RPO: LGX) engine and corresponding 8-speed automatic transmission recalibration. The TRIFECTA Performance Buick LaCrosse LGX powertrain calibration is an easy to install software performance calibration with an included flash loader 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 LaCrosse LGX.
The TRIFECTA Advantage Powertrain Calibration for the Buick LaCrosse LGX is meant for 100% stock vehicles. No individualizations or support for parts that do not function on factory calibration (if you have such modifications, be sure to check with us prior to placing order). Includes a TRIFECTA flash loader.
