Default Need Help Burning Very RICH!!!!

I have a 91 GT w/ a 8psi blower 30 lb injectors 255 fuel pump. My car burns so rich at times it dies and there is a strong fuel smell. I dont have a fuel pressure gauge but I know its rich. All this started when I had a new tranny installed. When I got my car back the MAF sensor went out and then it run better for a day or so. Could my fuel pressure regulator be out? I am just lost and need help,Thanks

P.S. By the way I am getting about 120 miles to a tank!!!

I sugges getting a guage and an adjustable regulator, then you can turn it wherever you want and lean it out, the leaner the meaner
