I have a 2008 Pontiac G8 GT with a 229/244 .615/595 113+4 cam and a circle D 3600 stall. This is the first car I have ever tuned and I got it to where it would start and idle so I built a tune up to go out and start tuning the MAF sensor now the car wont start and run. I've tried making different adjustments to the airflow final minimum and idle timing but still wasnt having any luck. When it would coast down a hill or be idling it would get super rich but even with the airflow adjustments to try and lean it out a little I still wasn't having any luck. If anyone could check it out and see what im missing or doing wrong that'd be awesome..
Looks to me like the Airflow vs Frequency table could use a little work toward the bottom. Try getting rid of the peak down low see if it fuels a bit better. I am no expert on this so maybe someone else with more knowledge can step in and give you a better place to start.
