This may be a stupid question, but if I have a MAF programmed for 32lb injectors and upgraded to 42lb injectors and am having my car tuned, do I still need to get a MAF programmed for 42lb injectors?

A custom tune will correct for the injectors.
No need to buy another MAF.

However, driving the car to the shop with a 38lb maf and 42lb injectors could be interesting
