Use either number but, stick with the number that you use for all of your future testing.
Most dyno shops that use the dynojet machines print only the corrected numbers(they also have the correction factor printed on them) so the corrected number would be the one to use for all comparisons across the board.
At a recent dyno day that our club sponsored, where 22 vipers ran on the dyno the average hp number(corrected) for a bone stock car was 406 rwhp, with minor mods like removing the rear exhaust and installing tubes and filters a few cars pulled numbers into the teens and one made 425. These were of course gen 2 cars ranging from 96 to 00 models.
Just some FYI,
