The 190 probably won't be enough. The pump needed will determined by the HP you make or intended to make. If it were me, I would go with either add a T rex to your existing or get a 255hp pump. Then go to a dyno and see what the air fuel is on a wideband. That way you can see if the injectors and fuel system are large enough to do the job safely.
