While not required with existing TRIFECTA CTS VSport calibration, this application-specific calibration offers the best experience with the Corsa exhaust system by optimizing engine and transmission characteristics for all drive modes. Tour mode (stock tour mode) delivers a factory driving experience, with a quieter exhaust note, for everyday driving. Sport and Track mode allow the engine to "rev out" further in each gear, combined with increased throttle demand to give off a more performance-oriented exhaust note. ECU dynamic recalibration in Sport / Track mode offers a performance over economy option, offering quicker turbo and vehicle response, a side effect of which is a more aggressive exhaust note at idle.
 
TRIFECTA's powertrain calibrations are tested and validated for various environments, such as cold/heat, elevation, and variations in fuel quality. Each vehicle type is validated on TRIFECTA's test fleet for a minimum of 100,000 miles and 100 hours of full throttle application prior to retail release. We make no compromises in comprehensiveness, safety, and power.
