The Mitsubishi Evo X is renowned for its performance and tuning potential. Among the most popular modifications to enhance its power are turbo back exhausts and ECU tunes. This article explores how much power you can gain from these upgrades.
Understanding Turbo Back Exhausts
A turbo back exhaust system replaces the entire exhaust path from the turbocharger to the rear of the vehicle. This modification improves exhaust flow, reducing back pressure and allowing the turbo to spool more efficiently.
- Improved exhaust flow
- Enhanced turbo response
- Potential weight reduction
Power Gains from Turbo Back Exhausts
On average, a turbo back exhaust can yield a power increase of 20-30 horsepower, depending on the brand and design. This gain is attributed to the increased airflow and reduced turbo lag.
The Role of ECU Tuning
ECU tuning involves reprogramming the car’s engine control unit to optimize performance. This process adjusts fuel maps, ignition timing, and boost levels to maximize power output.
- Increased horsepower and torque
- Better throttle response
- Improved fuel efficiency
Power Gains from ECU Tuning
With an ECU tune, drivers can expect an additional 30-50 horsepower. This improvement is particularly noticeable when combined with a turbo back exhaust, as the ECU can take full advantage of the enhanced airflow.
Combined Power Gains
When both a turbo back exhaust and ECU tune are implemented together, the cumulative effect can lead to significant power gains. Many Evo X owners report increases of 50-80 horsepower after these modifications.
- Turbo back exhaust: 20-30 hp
- ECU tune: 30-50 hp
- Total potential gain: 50-80 hp
Factors Influencing Power Gains
Several factors can influence the actual power gains experienced after modifications:
- Quality of parts used
- Type of ECU tune (custom vs. off-the-shelf)
- Supporting modifications (intake, intercooler, etc.)
- Vehicle condition and maintenance
Conclusion
Upgrading to a turbo back exhaust and implementing an ECU tune on a Mitsubishi Evo X can yield impressive power gains. With proper installation and tuning, enthusiasts can enjoy a thrilling driving experience with enhanced performance.
