Hey guys, i own a r33 gts25 non turbo, and was wondering if a ecu remap would increase power through out the whole rev range, plus remove the limiter? Although i currently have no mods, i heard that a ecu remap could give me some power. If this ecu remap is worth it, is there any places in melbourne that will actually do it, if so how much?? Also i use 98 ron fuel and was wondering if tuning the car to run just 98 ron fuel will increase power aswell?
