Check Engine Light Running Lean!?! 97 850 T5 Help! 850 1997

Check Engine light is coming on, and I get a P 171 (engine lean) code from a generic OBDII scan tool. The motor revs freely at idle, yet the under load the car is very sluggish, and there is a burning smell from something overheating. I believe the smell is the catalytic converter overheating. The ECU has been modified with TME/IPD program, along with a TME sport exhaust, but the problem persisits with a stock ECU. I have been told that a MAS (Mass Airflow Sensor) may fix the problem, any suggestions?!
The Volvo is a 1997(1996) T5 wagon, with about 98,000 miles.
Regards,
Pete
