I had mine in front of the turbo for a while as a draw through system. The fueling consistency was great, BUT........
Everytime the blow off valve opened on a shift, it would go super duper rich for a second.
If I tried to go from boost to idle, like after a burnout, or after I crossed the traps, the engine would stall from being too rich.
After is better I think.

a recirculating BOV woulda fixed that. So is that the ONLY reason you didnt like it in front of the turbo? cuz im trying to figure out the same thing.

My maf was placed 8" above the road and was taking alot of damage from road crap. The cable from the MAF to the PCM was really long and adding distortion. It didn't have a long straight run between the filter and the MAF, so it got turbulent airflow. It idled crappy and had alot of hiccups.
I converted to blow through for all around better running.

still there are many people running very streetable setups that are SD tuned.
thanks Chris.

I disagree with that. In my opinion SD is always the best solution for a forced induction car.

I run a MAF and it works great...of course, I'm not surpassing that magical 500hp mark. I would prefer SD in some circumstances, but don't you have to re-tune the car every time the weather changes?
IMO, if it's a daily driver < 500rwhp, I say stick with the MAF. If it's an FI track car...go with SD.

just your coment just goes to prove that SD is really the way to go!
