Here is what I have so far. What parameter if any needs to be adjusted?
LABELS Selection
Parameters Value
{C2901} MAF High Frequency Fail 1 1.000000 Hz
{C2903} MAF High Frequency Fail Limit 1.000000 failures
{C2904} MAF Low Frequency Fail 1 1300.000000 Hz
{C2906} MAF Low Frequency Fail Limit 6.000000 failures
{C2907} MAF Test Min Engine Speed 400.000000 RPM
{C2908} MAF Test Min Run Time 2.000000 Seconds
{C2909} MAF Test Min Batt Voltage 8.000000 Volts
{C2910} MAF Test Max TPS 95.000000 %

Question: In the EFI Tutorial, it provides info on changing the MAF fail settings. Does that mean I can leave the MAF pin plugged into the MAF? If not, how will the PCM read IAT?

According to the EFILive tutorial if the MAF has a five pin plug you must make provisions to get the IAT signal into the PCM.
The tutorial tells you to check the forums on how to do this.

Just a note that took me a while to figure out becouse it wasnt in the tutorial....I kept getting reduced engine power and throwing the p1514 code everytime I went above 4k I would have to shut the car off let it sit for a few seconds before it would re-start. If it does this to your car all you have to do is go to the c6101 table and multipy all values by 200% until you are done tuning everything......
