K-NASTY 2002-2007 Subaru WRX & STI E-Tune

Kevin Nash, or K-NASTY, is Circuit Demon's in-house shop tuner. He has been providing professional tunes since 2016. Kevin has tuned hundreds of vehicles ranging from imports to domestics, including Subaru, Mitsubishi, Chevy, and more.  Kevin highlights his work on various Subaru's from mild to wild. He prides himself on being conservative with his service to retain the reliability of the vehicle.  Why run a tune? The factory ECU calibration takes a lot into account; fuel economy, octane rating, reliability, etc. A new, more performance performance oriented map can dramatically improve the drive-ability, power band, and can tailor your car more to your driving style or goals. This is done through adjusting fueling, boost pressure, and engine timing.  Parts needed for this calibration:- Cobb Accessport V3 (Need one?
