anyone have a chip mod ?

Hey i was looking at getting something like..hypertech,or diablo sport tunner, but i cant find any for a 04 xterra. does anyone know about anything. I know all it does is waste gas but i was looking for fun.

thanks

depends if I am cutting or gaining,

cutting I will just eat the chip nothing on it, if I am gaining I'll go all out with cheese, bacon bits and zesty taco sauce maybe a few peppers also...
