- Upgrading the exhaust system if chosen.
Understanding Stage 2 Mods
Stage 2 mods take performance to the next level, requiring more extensive modifications. These upgrades often include additional hardware changes alongside ECU tuning.
Power Gains
Stage 2 mods can yield power increases of around 80-120 horsepower and 70-90 lb-ft of torque. This is achieved through more aggressive tuning and the installation of high-performance components.
Cost of Stage 2 Mods
The investment for Stage 2 mods is significantly higher, typically ranging from $3,000 to $5,000. This includes:
- ECU tuning software: $1,000 – $2,000
- High-flow fuel injectors: $400 – $800
- Upgraded intercooler: $500 – $1,200
- Performance exhaust system: $500 – $1,000
Installation Process
The installation of Stage 2 mods is more complex and may require professional assistance. Steps include:
