There is no real reason not to run MAF on a turbo car. The reasons people don't are: 1)intake plumbing gets complicated on multiple turbo setups. 2)most aftermarket ecm's don't support maf setups. 3)You have to keep buying maf's as you increase your power level. Too big a maf doesn't have enough sensitivity at low rpm, and too small is a restriction.
I used to be into 2.3 turbo fords (turbocoupes, SVO mustangs). They were maf. Well, actually they used an air door, but it was basically the same setup. They worked just fine.
