602065 / 602065 - Application Notes



OK you Altima horsepower junkies - here's some more!  By optimizing fuel/air management, the QR-Pro gets the most out of your 2.5 liter engine. We saw big increases at the front wheels and huge gains in proper air/fuel ratios throughout the power band. The unit wires directly to your stock ECU, unlocking the hidden performance of your Altima throughout the entire RPM band.  The QR-Pro is pre-programmed and is dual mapped (PERFORMANCE map and the VALET map). The VALET map lets you lend the car to mom without scaring her to death. These are preset maps that can not be re-programmed. Also provided with this unit is a mountable toggle switch, allowing you to switch between maps on the fly.  Another added feature of the QR-Pro is the included bypass connector that returns the ECU to stock programming mode.  Installation instructions are included. ***Will require use of premium fuel.***
