Description
With a stage 1+ Package you can expect peak power increases of 12%+ HP and 15%+ TQ. You can expect to get 10-20% horsepower increase throughout the whole rev range. Check out our Mods Guide to see dyno graphs of power outputs and for a good mod path for future modifications.
We are glad to provide custom E-Tunes for the 2015-2021 WRX based on our years of dyno tuning knowledge. With all the different performance part combinations, a one size fits all staged tune isn’t always the right choice. We take into account all the modifications you have along with your goals/expiations to give you the best driving/performing car. We also know the limits of these engines and know where in the engine rpms it’s safe to push them and where it’s not.
All of our E-Tunes utilize the latest Cobb Custom Features (CCF) maps to give you the best driving experience. Some of the features we set up on all tunes are:
- Remove the stock “rev hang”
- Full time closed loop fueling: We tune every car with full-time closed loop fueling. That means the front O2 sensor controls the AFR under full throttle ensuring the AFR is always spot on.
- Smoother boost for more linear power delivery
- Boost by Gear: All MT tunes have boost by gear. This helps your car hit close to boost target in all gears.
- High Gear Over-Boost Protection: We employ over-boost protection in 4th-6th to limit boost below defined rpms. An example is if someone goes WOT in too high a gear at too low an rpm, boost is limited to wastegate pressure to keep engine loads low and reduce the risk of engine damage.
- User adjustable Launch Control and Flat Foot Shift
