We present results from a preliminary assessment, via computer simulations, of the electron cloud density for the FNAL main injector upgrade at injection energy. Assuming a peak value for secondary emission yield deltamax = 1.3, we find a threshold value of the bunch population, Nb,th~;=1.25x1011, beyond which the electron-cloud density rho_e reaches a steady-state level that is ~;104 times larger than for Nb
