      Turbosmart makes two wastegate actuators for the 1.4 Turbo with two different spring pressures : 7 psi and 10 psi. You use the 7 psi for stock boost levels and or if you do not have a tune, but want improved build up of boost. You can use the 10 psi style if you have a aftermarket tune that can accomodate the higher psi spring for 5+ psi over stock boost levels on the factory turbo.
