Does a throttle bodie setup still need an afm?

On a street car with a very conservative VE characterisitcs then MAP is good, its great for accounting all atmospheric conditons.

Even with alphaN blending at lower rpm's to stabalise for pulsing map values, i've yet to feel nice with a full Speed density setup. The nature of the MAP readings on ITB's once you are past but a few percent throttle becomes very small change for very large throttle change and the map basically becomes wasted unless you have a large resolution to play with.

On road going cars with ITB's we run mostly AlphaN and get great economy, much better throttle response, use the map sensor to correct for baro conditions.

Speed density takes alot of time setting up and mapping, and not many people are willing to pay for an ECU that will provide a smooth map with lots of breakpoints, aswell as the time spent mapping it to where i would be 100% happy.

Its just preference and most of our cars run so much overlap that you cant idle using map.
