Expertly calibrated and meticulously refined, DME Tuning’s ECU software is guaranteed to give you MORE of a good thing. More horsepower, more torque, and a more exhilarating driving experience by delivering usable power through improved throttle response and torque management. With additional ft. lbs. of torque through the mid-range, acceleration out of your favorite corner and onto the straight is noticeably quicker throughout the rev range. DME Tuning saves your stock/factory ECU settings so that you can revert your vehicle back to stock settings at any time.

OBD tunes allow customers to simply plug in a cable and upgrade their ECU. We send you an OBD cable and remotely tune the car using remote desktop software called TeamViewer. You will need a Windows 7+ laptop for this process.
