I recently in stalled the spacers and large throttle body on my 2005 maxima.and i haven't really noticed any difference in power,even at high rpms any suggestions?

You made it worse. Put it back to stock.

How come every maxima i see had these mods.would you mind elaborating a little?

So that the owners can look cool to pick up chicks. Or dudes.

Unless you are tuning, any performance mod you add is not only useless in terms of performance, but can actually have a negative effect on performance as the stock ECU is now confused from receiving incorrect sensor data throwing all stock programming out the window.

ahaaaa!yes i am getting a tune and dyno.also im new to this(obviously) so after the tune I'm sure i will see a difference in performance.

Then you need to discuss this with your tuner. He'll tell you what you need and what he is set up to manage.

Usually the Big Bore TB shows more responsiveness and more linear throttle inputs...as well as the NMP spacers providing more torque. I noticed the torque factor with the installation of the NWP spacers. Maybe you have a defective VAIS solenoid it usually makes the car feel ball-less if it's not operating. Test your solenoid first they usually fail with an open solenoid using VOM continuity test.
