TRIFECTA presents: Chevrolet Silverado / GMC Sierra (Gen V V8, 5.3L, 6.2L) MY2014--2018+ Powertrain Calibration Reprogramming (flash tune)
TRIFECTA is pleased to announce the immediate availability of the 2014--2018 Chevrolet Silverado / 2019 Silverado LD and 2014--2018 GMC Sierra / 2019 Sierra Limited vehicle software recalibration (reflash) for vehicles utilizing either the 5.3L V8 or the 6.2L V8 with either the 8 speed automatic transmission (8L90 / RPO:M5U) or the 6 speed automatic transmission (6L80 / RPO:MYC). Two wheel drive (2WD), four wheel drive (4WD) and all wheel drive (AWD) variants are supported. Specific gains over factory calibration are up to (uncorrected) 45lb-ft of torque and 19 horsepower with no vehicle modifications beyond the updated software calibration.
 
TRIFECTA's 2014--2018 / 2019 Limited full size truck recalibration is complimented by a fully developed 6-speed or 8-speed (depending on application) automatic transmission calibration to support the increased power delivery profile and to offer dramatically improved driving characteristics from everyday driving maneuvers to towing and hauling. The complete powertrain calibration also includes ESC (Stabilitrak) and, for four/all wheel drive (4WD/AWD) equipped models, TCCM (transfer case control module) program enhancements.
 
All 2014--2018 / 2019 Limited full size truck calibrations also include TRIFECTA's exclusive "tri-mode" DSVM (driver selectable vehicle modes). Choose between TRIFECTA Sport mode, tow/haul mode, or ECO mode, on the fly using existing vehicle controls (see full details below).

Fuel economy is improved (up to 2.4MPG observed), dependent on fuel grade and driving conditions 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 Full flex-fuel / E85 features retained Tested on all available grades of fuel (87, 89, 91, 92, and 93 octane) and ethanol blends from 10% to 85%
TRIFECTA Performance Active Fuel Management (PAFM) 
 
The L83 offers V8/V4 mode. GM has succeeded in making V8/V4 transitions (AFM, or Active Fuel Management as GM calls it) extremely smooth, such that in most cases they can't be noticed. However, some customers may have exhaust or other modifications that cause the truck to produce an undesirable exhaust note while in V4 mode. TRIFECTA exclusively offers three options with regard to adjusting AFM parameters with this product:
AFM available/active in all drive modes (default) AFM disabled in Sport mode AFM disabled entirely
Specifications of the TRIFECTA Performance 2014--2018 / 2019 Limited full size truck 6-Speed / 8-Speed automatic transmission TCM calibration software reprogramming:
Added vehicle drive modes (TF Sport, tow/haul, and stock) Improved shift times in adverse shift patterns Improved shift logic - shifts are progressive and purposeful Does not shorten transmission life or increase cooling requirements Retains all OE diagnostics and TCM functionality Retains all OE error code reporting and functionality  
Supplementary Featureset of the TRIFECTA Performance 2014--2018 / 2019 Limited full size truck powertrain calibration software reprogramming:
TRIFECTA Interactive Driver Selectable Vehicle Mode (Select-a-Tune MKII): Cruise System Armed = ECO Cruise System Disarmed = Sport Tow/Haul = TRIFECTA Enhanced Tow/Haul Mode (Overrides Cruise System Selection) TRIFECTA ECO Mode: Up to 2.4 MPG improvement by dedicated TRIFECTA ECO mode prioritizing fuel economy in engine calibration profile and transmission shift strategy Alternative Driver Profiles layout included with individualized calibration TRIFECTA Octane Adaptive MKII featureset will bias for lower octane fuels (multi dimensional airflow knock and timing decay tables, not just high/low) Improved fuel economy while towing with alternative TOW/HAUL mode Installation Notes:
Estimated installation time of ~20 minutes Premium fuel is recommended for maximum power output, but not required  
Additional information and availability:
This powertrain calibration includes a TRIFECTA powertrain calibration file specific to your vehicle and includes an EZ Flash Cable (TFEZ010U) 5.3L hybrid applications using the ‘R’ VIN code (RPO L8B) are not supported.  
TRIFECTA Advantage:
If your vehicle is stock, or has certain modifications which "just work" and do not require tuning, you can simply plug and play with our TRIFECTA Advantage calibration. Advantage customers receive full customer support for as long as they own their vehicle. Custom tuning is not offered at this tier, and the price reflects it. It is a great entry level option if you want to get the most potential out of your vehicle with just one mod!
