Guarantee it does not with just an S-AFC and the proper MASS in there if your vehicle does truly have 850cc injectors and no other modifications. Now if you have a 2g mass in a 1g, rheostat on your coolant temp sensor, base timing is jacked up, massive fuel leak, different camshafts, or other tuning solutions, all bets are off. But a stock car, on 850cc injectors, with the correct fuel pump backing them, does not just "start and idle fine" with 850's zero'd out for correction, assuming your S-AFC is installed correctly.

Verify your settings are correct for the vehicle. 4 cylinder, arrow proper direction, high/low throttle points spaced our correctly, RPM points spaced correctly, proper airflow sensor selected.
With a slightly larger than factory turbo, I would venture on this range to run the vehicle.
Low assuming 1k rpm splits like factory
-15, -15, -16, -16, -16, -15, -15, -15
High
-11, -11, -11, -11, -10, -10, -10, -10
Assuming on boost leaks, sanity for boost levels (I noticed you did not mention a BOV upgrade or intercooler upgrade, so you are probably in the 12-15psi range), and good gas, you
should be okay.
Disclaimer: Always have your vehicle checked by a professional. Log AFR, timing, knock and torque whenever possible to make sure your changes are benefiting the vehicle power output. Street tuning can never replace dyno tuning regarding controlling the vehicle and safety.
