FW190A-4 engine overheating problem

While flying the FW190A4 this week i noticed strange engine overheating problem in Air cooled engine wich doesnt make any sence. Even an average mechanic knows that an Air cooled engine doesnt overheats too easy, it doesnt mean that will "never"of course, with extremely conditions of enviromments and WEP use Oil will boil anyway however overheat QUICKLY its very very difficulty compared to the water cooled system counterparts.
The plane got NERFED significantly and i want to ask if it is possible to bring back with the correct engine like it was before,
