fouling plugs

Hey running a speed density tune, car has been doing really well and went to track today and is now fouling plugs! not just one but all plugs. Injectors are at 98% duty cycle already but have been doing fine for a long time now. What could cause this???? Maybe the MAP sensor bad? I don't think it is the injectors, but maybe. It is a friends car but input would be great.
