Mclaren 650s ECU Tune

Expertly calibrated and meticulously refined, Pure Performance’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. Pure Performance 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 handheld and upgrade their ECU. We ship you a My Genius handheld device which requires a Windows 7+ computer to pass files in between. All the instructions are in the box. You will read the car with the device and email us the stock file. We will email you a tuned file based on your request which you load into the device and flash the car. The device holds the stock and tuned files for easy back and forth.
