Bud the temp variation is slight and the ESS kit allows for variation of around 1 psi either way anyway
Also ECU's adaptation would also take care these normal variations
I have done the blower on two of my M3s and had no issue ever.
In winter my temp are around 5-15 deg and summer 20-35 deg so similar to your temps
I have seen a drop in perceived performance now that temps have warmed up.
