Haha you have a 00-04 Xterra. Sometimes a lack of power is normal...its a curse we all bear for having a cool SUV . If you don't have a S/C, and you're feeling a little less-than impressed by the power you're getting, you might want to look at doing an intake/exhaust combo, even if you aren't considering any other mods. Its worth it, and you'll actually be able to pass other vehicles while going up an incline!
