I just got myself a new 350Z( well new to me 2003). It has an intake and exhaust done to it. I was wondering what could I do out side of FI and TT to get more Power. Will an ECU flash help? Also the car seems to accelerate better with the VDC turned off. Does it or is it just me?

 

Congrats on the car.

It should feel like you're accelerate slightly faster with VDC turned off because you're turning off the computer hand-holding.

 

Outside of FI or TT? Well, NA bolt ons is your only other choice. (Am I missing something?)

What kind of intake and exhaust does it have?

You can consider a plenum, crank pulley, headers, cats and some other stuff I am sure folks will chime in here and suggest.
