No, you got it wrong. A bolt on 1M can also put 100 hp more, even more than that in some cases. Actually this here doesn't show anything like you say. It effectively shows the opposite data, that E92 M3 and 1M has merely 30 whp difference each stock. My car with just the exhaust (stock down pipes) is only 23 whp shy of a E92 M3 on the same dyno, before exhaust it was 30 hp. Charts and info are posted somewhere in this thread and actually confirms the same findings of other people. This is a very low reading Mustang dyno if that matters.

Another data is stock to stock difference in torque, at the wheel is more than 100 lb.ft, which makes 1M tq 60% higher than the M3. It peaks around 2500 rpm and stays close to peak till around 6000 rpm. M3 has one of the flatest tq curves I've seen despite lower peak tq, lovely as well.

To put it in a nutshell, 1M has 90% of M3's hp and 160% of its tq. Weight difference vary from market to market according to standard equipment but I heard it is around 250-300 pounds in US, I know it is 80-100 kg. in Europe.
