Great Gains

Ewan’s low low mile brand new 2018 STi in for the FBO/Flex fuel treatment making some great power. This package retains stock like drivability with huge power and torque increases with ethanol to help keep the car safer. We rounded it off with some small suspension and aesthetic upgrades to round it off. Perfect daily driver!
