Yes—ECU recalibration is required for safe operation and maximum power.

Can a boost controller increase WRX horsepower?

With proper tuning and supporting mods, higher stable boost targets can unlock more power.

Is a WRX boost controller safe for daily driving?

Yes—when installed correctly and calibrated via ECU tuning.

Which brands are most popular?
