Product Description

By optimizing fuel/air management, the QR-Pro gets the most out of your 2.5 liter engine. The QR-Pro increases power at the front wheels while improving drivability throughout the rev-range via optimized air/fuel ratios.

The unit wires directly to the stock ECU, unlocking the hidden performance of the Nissan 2.5L engine. The QR-Pro comes pre-programmed and is dual mapped (a PERFORMANCE map and a VALET map). The VALET map lets you lend the car to others without worrying about how much “fun” they are having.

These are preset maps that cannot be re-programmed. Also provided with this unit is an easily concealed toggle switch, allowing you to swap between programs on the fly. Another added feature of the QR-Pro is the included bypass connector that returns the ECU to stock programming mode. Wiring and installation instructions are included.

***Will require use of premium fuel.***
