I absolutely love it!
I bought the stage 3 chip for my 2016 Nissan Maxima. Factory listing is 300 hp, after having chip stalled for 300 to 400 miles, I have hit 354 hp and seen a 3 to 3.5 Mpg increase city. The car is running smoother than ever and that's with a 182000 miles on it. I drive it for a living. I highly recommend this product! Along with the monitor and Dashcommand app.
