Good product for the $
It took me about 10 minutes to install in my driveway. The power gain is subtle,and noticeable. I have a K&N 63 series added as well and the sound from that changed a little when accelerating and seemed a bit more responsive. The gas mileage gain is very little,.3 more mpg than before. I recommend putting after market (JET) mass air flow sensor in when you add the tuner, I had my check engine light come on after the first hard throttle. The factory MAFS cant handle performance tune.
The installation are is difficult
1st of all they sent me the wrong installation instructions and after looking around on the internet I found installation instructions. Still the area they expect you to put the main unit there isn't room to put it, so u have to put it up in back and zip tie it to other structure.
