Is it worth it? please help!

I just got my black 06' GP and it is not SC casue i couldn't afford it. In the near future i am hoping to do some mods like, headlight covers, lowering, tints, and for performance with the incredibly limited oamount there is so far, cam, airintake, maybe valvetrain. So my question is has anyone heard of any company realeasing a ECU or PCM upgrade or something? & should i even worry about performance at this point or just looks and maybe wait a few years and trade in for a SCed one? and, can i switch the rear bumper lower gray lip with a dual outlet on and run duals, from a company like corsa or SLP? instead on custom fab.?

I had a 2001 GTP, and just got into a 2006 GXP. I have rented the regular GP without the blower too. If you can afford it, the GXP is unreal. The power increadible, as is the rumble from the V-8. It is easy (and inexpensive) to soup up the blower with different pullies though.
