Su-27SM Flanker Question

Hi all

I have been looking for some updated information about the Su-27SM, but many sources seems to show different informations. Maybe someone can help me.

Is the Su-27SM equiped with the same avionics package and engines of those of the Su-27SK?
Some sources says that the Su-27SM is equiped with AL-31FM1 with 12% more thrust and AESA radar. Is that true?

Thanks in advance
