dude, i brought this up months ago and I got reeeeemed by NICO members b/c people are just rude. i'd just say, go ahead and install it in your jeep. it's going to be different in you maxima b/c your electronic ignition control, and MAF sensor. Also, your 02 sensors will each need an EFIE Sensor bypass so your ECU doesn't dump in more fuel b/c of a larger Oxygen reading in the exhaust...the computer is going to think that the car isn't burning all the fuel properly so it may constantly retard the timing, and air/fuel ratio.
read this, and utilize all the links
