ECU's in general on a base Maxima won't do much but possibly increase the rev limiter a bit and possibly get rid of the speed governor. If you get headers, intake and the other bolt ons it could increase performance somewhat. The best "bang for the buck" on the '03 performance wise would be headers.
Technosquare started selling reprogramable ECU's fot '02-03 models but I don't know if they still do or not.
