Product Description


The Cobb Tuning Accessport for your 2015 Subaru WRX & STI is all you need to start tuning your car and unleash additional power even in stock form. With the pre-installed performance MAPS, you will noticed instant power as the system optimizes your air/ fuel ratio, ignition timing, and boost.

Currently the system comes equipped with a Stage 1 MAP for non modified 2015 WRX & STi's (more MAPS to come), but as always a custom tune can be done through Accesstuner.

In Stage 1, your STI will gain an overall of +30% Horsepower and Torque over stock at 3,800RPM (Peak Gains of +4% HP and +22% TQ). And on the WRX an overall gain of +17% Horsepower and Torque over stock at 3,400RPM (Peak Gains of +11% HP and +11% TQ) will be seen.

As if the reflashing wasn't enough, the AP will monitor your fuel economy, provide performance tests such as 0-60mph and 1/4mile times, function as a gauge, and view/ eliminate CEL codes.
