If you were to go with a Holley EFI system, like the Terminator X Max, then a MAF is not needed.

And to add to this, you can also run the GM stuff without the MAF. It will automatically go into SD (speed density) mode when MAF is unplugged. Any good tuner can make the setup work properly. Really boils down to preference. I prefer the SD tuning myself, but I don’t drive mine across the country where multiple weather and elevation changes would work better with a MAF setup. Both style setups have their pros and cons.
