Is it worth spending $400 for an aftermarket oil pump. I am doing a 95" - stage II mod to a 2003 Road King. I see in the Feuling oil pump product description, with the higher volume and pressure, a 2 horsepower and 3 ft-lb of torque gain over stock. A friend of mine recommended a Baisley Spring that I'm going to install and that should suffice with the stock oil pump with my build. Any ideas or recommendations?
