Yep depending on how much fuel system headroom you have. I see a 1-2 psi difference in boost going from 90 degrees in the summer to 45 degrees in the late fall here in Northern Indiana. I do have plenty of fuel system for E60 so I can run it year-round. The +30's run around 5.3ms in Summer and 5.8ms in late Fall. When I was running LT4 high side I had to drop back to E40 in the fall.
