Maybe you should bring the fuel level back to zero. If you are running stock injectors then you really dont have to touch the fuel levels unless you are tuning the car. Adding more fuel to a rich mixture will only make things worse. Are you running a catalytic convertor? Test pipes and rich exhaust causes lots of popping in the exhaust. More power is made with a leaner mixture...to an extent. How's the wiring on the mass air flow sensor? A bad reading could cause your car to run rich too.
