But if the temp is that high, then I would try a different maf, or clean it. It might be dirty and reading wrong.
 
If you are using a 98 ecu your numbers are off a little.
It won't pull timing until 50* C.

You should really log Air Temp while driving, it will be much cooler once you get some air flow.

I have found that if the thermistor inside the MAS gets fouled by oil it causes a false high temperature reading. Its a small pinkish orange diode that you can see sticking up into the airflow. Make sure its cleaned off well. Spray it with some carb cleaner. The grease/oil across the diode can be partially conductive, throwing off the resistsance.
