The best performance mods for that car are making sure it is maintained and kept serviced, so that it still performs as it did new.
I'll never understand the desire to neglect a car for 100k miles and then think bolt-ons will somehow improve it.
Grab the FSM at infinitiservicemanual.com and do ALL of the maintenance and upkeep that should have been done previously, and you'll be impressed with the car.
No ECU tuning that I'm aware of, but since you already have the intake and exhaust, it's time to replace the non-glamorous stuff.
