What is a stage 1 tune on a WRX?
A stage 1 tune on a Subaru WRX is a popular and relatively simple modification that can unlock significant performance gains without major engine upgrades. This article will provide a detailed overview of what a stage 1 tune entails, its benefits, and how it differs from other tuning stages.
What is a Stage 1 Tune?
A stage 1 tune, also known as a stage 1 ECU (Engine Control Unit) tune or flash, is a software modification that optimizes the engine's performance parameters. This tune is typically the first step in a WRX owner's journey to enhance their vehicle's power and responsiveness. The stage 1 tune is designed to work with the stock engine and hardware, making it a relatively affordable and accessible upgrade.
Key Benefits of a Stage 1 Tune
The primary benefits of a stage 1 tune on a Subaru WRX include:
- Increased Horsepower and Torque: A well-executed stage 1 tune can increase the WRX's horsepower and torque output by 20-30 hp and 30-50 lb-ft, respectively, without any other modifications.
- Improved Throttle Response: The tune optimizes the engine's air-fuel ratio and ignition timing, resulting in a more responsive and engaging driving experience.
- Enhanced Drivability: The tune can smooth out the power delivery, making the WRX more tractable and easier to control, especially in daily driving conditions.
These performance gains are achieved by adjusting the engine's mapping, which controls factors such as fuel injection, ignition timing, and boost pressure. The stage 1 tune is designed to work within the WRX's factory limitations, ensuring reliable and safe operation.
Differences Between Tuning Stages
While a stage 1 tune is the most common and accessible tuning option for WRX owners, there are several other tuning stages that offer progressively more power and modifications:
- Stage 2 Tune: This tune typically includes additional hardware upgrades, such as a high-flow exhaust system and a larger turbocharger, to further increase power output.
- Stage 3 Tune: This advanced tune often involves major engine modifications, such as forged internals, to support even higher levels of power and performance.
It's important to note that as the tuning stages progress, the complexity and cost of the modifications also increase, as does the potential risk to the engine's reliability and longevity. A stage 1 tune is generally considered the safest and most cost-effective way to unlock significant performance gains on a Subaru WRX.

| Max HP | 23.1% | 202.5 hp vs 158.3 hp @ 3200rpm |
What will a Stage 1 tune do?
As a result, stage 1 remaps are often used to increase the power output of a vehicle. In addition to increased power, stage 1 remaps can also provide other benefits, such as improved fuel economy and reduced emissions.
What does tuning a WRX do?
Think of tuning as recalibrating your WRX's brain (the ECU) to understand and work with the hardware upgrade (the downpipe). Tuning involves adjusting parameters like fuel delivery, ignition timing, and boost control to work optimally with your specific downpipe and other modifications.
