Does a stock 300 x tuner have different length runners like a 225 efi ? For example my stock merc tuner on my 225 efi the port side is longer compared to starboard side this is because starboard cylinders are stacked higher , that said how come mad or hydro-tec are equal ? Why not cut stock tuner in middle casting line , then smooth out orig to remove rough foundry casting lines , is this the wrong direction ? I'm thinking it will work better than after market tuners because it will have different length runners and no restriction . Any thoughts ?
