None PAI model versus QGSP_BIC_EMY

Dear experts,

I'm doing a simulation of energy loss of mono-energetic protons (energy 20-36 MeV) in 300 um thick silicon box that is placed in vacuum. To get the deposited energy I use QGSP_BIC_EMY, QBBC and PAI physics lists. When I compare the mean energy deposit from these models for given proton energy I see that pai model result is systematically below QBBC and QGSP_BIC_EMY, see

The step size in Silicone is limited to 30 um for QBBC and QGSP_BIC_EMY.
Could you tell me what should be changed in the settings of pai model in order to make it compatible with QBBC and QGSP_BIC_EMY?  Pai model that I use was adapted from the example TestEm8.   Thanks in advance for your answer.
                      Best regards
                                         Filip
