That is just a warning that you are trying to exceed more than 100% duty cycle.
It potentially means your injectors are too small, your fuel pressure is too low, or there may be some other problem causing a large PW to be commanded such as a trigger error.
If you attach a log and your tune we may be able to confirm the problem.
