2018 Subaru WRX STI – Stage 2 +40kW (video)

The Subaru 2018 WRX STI is quite the package straight out of the box. In factory form the STI’s EJ25DET engine produces 221kW and 407Nm. The owner of this car came to us in the hunt for some more grunt. We suggested our Stage 2 +40kW performance package.

Power achieved:

195kW @ 5500rpm (at the wheels)

 

Improved by Tunehouse:

From the factory the Subaru WRX STI’s power curve has a few a flat spots. By custom dyno tuning the STI on the Tunehouse dyno we eliminate these flat spots by making the power delivery come on stronger and more linear. The end result is a much more meaty mid range as well as more power up top. Check out the video below to see (and hear) the dyno results.
