The performance chip was fitted to my 2012 Nissan Quest within two weeks. After following the installation and setup instructions (*very important to unplug the car and leave it overnight) the device works very well. After reconnecting the battery, the car started and idled as usual. As soon as I started driving the car, the difference was felt almost immediately. I've noticed that I don't have to press the accelerator hard to get the car moving at 'normal' speed from a standing start. The car seems stronger and it really shows. The CVT seemed to run a little smoother. Possibly due to the added and improved torque ratio. YES, I tested it several times under straight line acceleration and it came out with more power. Currently my gas mileage doesn't seem to have improved (perhaps due to my "testing"), but this review is ongoing. Mileage certainly hasn't decreased, which in itself is a plus given the extra power I'm experiencing. The device itself looks very nice, and its extra power really complements the car (Nissan Quest 2012). Your technical support was outstanding. Installing the device was not difficult. On my car, this was more of a challenge due to the location of the IAT wiring harness. I like the fact that the product comes with all the installation hardware and helpful tips. The unit mounts next to the firewall where it appears to be factory installed and does not obstruct access to the airbox and air filter. So far he has really delivered the goods. Good product.
