system leans out for cold conditions maybe the you could try cleaning maf sensor

How do I go about doing that, and would that solve my loss of boost pressure and the back firing?

get an electrical component cleaner and take the breather tube off with maf on if \t and clean it it may cure your issues that is as very hard code to figure out
