2004 Performance Chips?

I am wondering if there are any performance chips out there for the 2004 Maxima and if anyone has any recommendations. I'm not sure if the computer is the same for the '04 as any other year, or if I need one specific for 2004. Does anyone know anything about this?

its prob a lil early i would think, but not sure if its like the 5th gen motors and electronics and all of that

the motor is exactly the same as the 5.5 gen, it just has a different computer contolling it. so yes, you will need a specific chip. and i haven't heard anything about a chip for the 6th gen yet, it is still very new
