It only means it would be safer to request more boost. If you want to request more load, request more load.

If you want to debug KFMIRL you'll need to log mifa/milsol/misopl/mimax

Quote
The stock KFMIOP map is at most around 80%, so increasing the last column of KFMIRL is not sufficient, unless you increase the last column of KFMIOP. Done properly, mimax should be safely high enough to never limit torque request, such that it is higher than mrfa from KFPED.

Quote
If there is requested load intervention, you will see mifa following mimax instead of mrfa, and thus a different rlsol result from KFMIRL than expected.

Look at injector dc and lambda control.

You're out of fuel, req less boost up top.
