Certainly wouldn't expect hp gains but the difference in how she drives now is noticeble and the sound is just awesome compared to before, for autocross I think this is right on as your not doing high rpm driving its lots of sharp little corners and that is where the 1nzfe was weakest having that dead spot in the throttle.

After I get a set of exhaust headers made I will look at a cam regrind from Franklin cams here in auckland, they like messing with toyotas and they have done them before as we use the 1nzfe as a jetboat engine here a lot.
