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

Alvin Phan –
Cannot say enough kind words for JM Auto and Devin who tuned my car. Great communication and definitely is detail oriented when it comes to making sure the tune runs well. I went with a flex fuel tune for my 2017 WRX and cannot be more happy! From start to finish, the communication and knowledge was top notch. Highly recommend!
