Dyno Tune Thursday – External Wastegate 2013 STi breaks 300WHP

This 2013 Subaru STi made great power with the inclusion of an external wastegate and fueling upgrades to support the increased airflow.  If you’re looking to maximize the power on your turbo car it is important to remove exhaust restriction and have plenty of fuel to meet the demands of the engine.
