I replaced my fx1 pump with a superjet pump. I got the pump shimmed perfect, midshaft installed. The engine originally had 1mm shims on only the pipe side of the engine. Since the midshaft is in the exact same place, should I place the shims in the same place on the engine? I tested with no shims and the 1mm shims and honestly couldnt really tell a difference
