Reducing rotational weight shows greater gains in engine output than just dead weight a car has to move.

Your injectors need to be sized according to max engine load needs. Detailed tuning/calibration may be able to help you recover on the small load end, but you have to size to keep from them running 100% duty cycle at max engine load.
