I figured this would be the best place to post this question, if not let me know. I found a company online called Tweaked Motorsports,
www.horsepowerchip.com that makes a performance chip that will work on the Xterra. They claim a 17-20hp increase but I seriously doubt it is that much. Does anybody know if this is worth getting or is this just some cheap resistor with a fancy sticker that won't do much except make my gas milage even worse? Any feedback would be good, thanks.
