2015 Subaru WRX STI + COBB Stage 1 Tune Review & Drive Cobb Accessport Product Link - http://amzn.to/1OZJNlF Subscribe for new videos every Wednesday! - https://goo.gl/VZstk7 The 2015 Subaru WRX STI features a 2.5L boxer engine producing 305 horsepower. With AWD, limited slip differentials front and rear, and wide tires, it has plenty of available grip. Major changes for the 2015 model year include a more rigid chassis, stiffer suspension, torque vectoring, and a tighter steering ratio. Overall, the changes lead to improved handling and better steering. This particular STI also features a COBB Stage 1 91-octane tune, which improves low end torque and overall power. I also test the 0-60 times before and after reflashing the ECU. Is the 2015 STI better than the 2014, and how does it drive with a tune?
