- Improves fuel efficiency
- Price range is around $300-$600
3. ECU Tune
An ECU tune modifies the engine’s computer settings to optimize performance. This can lead to significant gains in horsepower and torque, often exceeding 50 HP.
- Customizes fuel maps and ignition timing
- Can be done via handheld tuners or software
- Costs typically range from $300-$700
4. Upgraded Intercooler
Replacing the factory intercooler with a larger, more efficient unit can help lower intake temperatures, which is crucial for maintaining performance, especially under boost.
- Reduces heat soak during high-performance driving
- Can support higher boost levels
- Typically costs between $400-$800
5. High-Performance Spark Plugs
Upgrading to high-performance spark plugs can improve ignition efficiency and overall engine performance. They ensure a stronger spark, which is essential for maximizing power output.
- Enhances combustion efficiency
- Can improve throttle response
- Cost is usually around $100-$200
