Nothing wrong with them having a delta of 1-2psi tire to tire and across all four.
However, a. you should be able to get then closer (better auto-shut off inflator?) b. should consider raising the cold tire pressure a bit if on any stock size tire/wheel combo (say 46psi all around, or even 48psi)
c. set your own TPMS default nominal pressure (use the TPMS sensor reset menu)
