2015 Subaru WRX STI COBB Stage 1 Tune Review – Video

The 2015 Subaru WRX STI features a boxer 2.5L already potent motor producing 305 horsepower. With AWD, limited slip differentials front and rear, and wide performance tires, it has plenty of available traction. 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 Subaru WRX STI also features a COBB Stage 1 91-octane tune, which improves low end torque and overall power delivery. The reviewer also tests the 0-60 times before and after tuning the ECU. Is the 2015 STI better than the 2014, and how does it drive with a tune?
