diff spring rates have different tension. the higher the tension is and the bigger the spring is. the more its gonna hold the valve. down. thus creating more boost pressure. general rule of thumb is you can saftley exceed your spring by double. so if your spring is 5 psi. the max you should safely go is 10 psi. so as the wastegate deosnt creep/spike
