The EcuTek ECU Stage Reflash is designed for Re-programmable Subaru WRX, WRX STI, Forester Turbo, Legacy Turbo ECU's between 2001-2005. Our Stage reflash options smooths out the entire band, offers a linear power curve and improves the low-end torque and response while maintaining a very powerful, consistent and reliable tune. We have developed maps for a wide selection of intakes and the numbers represented below are based on the OEM intake system with or without an upgraded panel filter. We have found aftermarket intakes are not necessary for getting the performance you desire out of the vehicle, although we can cater to any intake system. Here are Delicious Tuning's figures for the following Stage(s)

How to determine if we can reflash your ECU with Stage maps or Custom mapping.
1. The ECU label states "Made in Japan"
2. The ECU label states "Denso"
3. The ECU has a five plug harness
4. The ECU has the letters "AF", "AG", "AK", "AJ", AH", "AL", followed by three numbers "xxx"
5. The ECU is most likely compatible
