To put it another way... of course 98% of individuals are going to say that the stock piston isn't capable or is too weak for XXX power. That is because they lack the skill set necessary to make it work to it's full potential. Forged pistons are a crutch that allow one to be terrible at engine config and worse at tuning because forged piston withstand the abuse of ignorance at the cost of mileage capability and reliability not to mention quintupling the cost of said engine.
