Overview
The Stinger GT 3.3T uses the Continental SIM2K-260 ECU on the Lambda II twin-turbo V6 and is one of the strongest Korean tuning platforms in this group. The stock file leaves significant room in boost pressure, ignition, and torque calibration, allowing very noticeable gains from Stage 1 while preserving street manners. Because the engine already makes strong low-end torque, careful tuning creates an especially broad and aggressive powerband that customers feel immediately. Confirmed OBD flashing makes it an excellent remote performance package with no ECU removal needed.
Key Features
- Excellent 3.3T tuning platform
- broad torque gains
- OBD flash via BitBox
- stronger spool and upper-load power
- Stage 2 suits catless downpipes and intercooler
