CADILLAC CT6 3.0L TWIN TURBO V6 (2016–2019)
STAGE 1 & STAGE 2 PERFORMANCE SOFTWARE
OVERVIEW
Our performance software for the Cadillac CT6 3.0L Twin Turbo V6 (LGW) delivers major improvements in horsepower, torque, throttle response, and drivability. All calibrations are developed in-house and engineered specifically for the LGW twin-turbo platform using advanced load, boost, ignition, torque, and airflow modeling.
Stage 1 is designed for completely stock or lightly modified CT6 models.
Stage 2 is intended for vehicles equipped with upgraded intake and exhaust components to support increased turbo airflow and load.
WHAT STAGE 2 INCLUDES
Stage 2 consists of a complete individualized recalibration of the ECU. All major engine parameters—boost targets, ignition timing, fuel delivery, torque limiters, throttle tables, load targets, and airflow modeling—are optimized to support:
- High-flow or catless downpipes
- Aftermarket cat-back exhaust
- Upgraded cold air intake
This results in stronger mid-range torque, faster turbo spool, smoother power delivery, and maximum safe performance.
FEATURES
- Speed Limiter (Governor) Removal
- Sharper Throttle Response
- Rear O2 Delete (DECAT) Included in Stage 2
- Optimized for 91–93 Octane
- Improved Fuel Efficiency
- Fully Custom ECU Reprogramming
- Enhanced Responsiveness & Drivability
- Optional Datalog Review & Optimization
