We are excited to announce that we have added software support for some popular JDM Subaru models. You can now tune your ECU with our advanced software and get the best performance out of your engine. Base maps are also available to help get you tuning quickly.
JDM 2003 – 2006 Forester STI SG9
Base Map Gains: +50 whp, +46 ft-lbs
The JDM Subaru Forester STI is a rare and powerful version of the popular SUV, with a turbocharged 2.5-liter EJ255 engine that produces 261 bhp and 279 lb-ft. Our base map gets you more performance than a much newer EJ257 at 310 bhp and 325 ft-lbs.
JDM 2003- 2006 Legacy B4 GT and spec.B, BP5/BL5
Base Map Gains: +10whp, +53 ft-lbs
The 4th generation JDM Subaru Legacy BP5 or BL5 with EJ20X or EJ20Y received twin-scroll turbos and dual AVCS for better drivability and low-end torque but the stock tune is so tame that you can barely tell! This can all be fixed with our software and tuning. Greatly improved throttle response and low to mid-range torque makes the car much easier and enjoyable to drive. The fuel economy gets better too. There are really no negatives to tuning these engines.
These cars have been available in the Beta version for quite some time now, so you can rest assured they have been well tested.
We are always working to expand our software support for more Subaru models and engines. We can add almost every phase-2 EJ engine and some FA and FB engines too.
Stay tuned for more updates and happy tuning!
