Boost Control Solenoid for all Rover 75 and MG ZT 1. Wastegate control is set to around 30 psi on factory turbo. That is the entire boost control system. Damage can occur when wear in the boost sleeve causes insufficient line pressure in reverse. This kit was specifically designed to handle higher base pressure in high performance applications and to improve the reliability of the governor solenoid in normal use. It was done by the previous tuner for some reason. To have control over this, theres a T in the line and off the T is the solenoid, it bleeds off pressure so the wastegate sees less than the real pressure, so you can basically get to twice the wastegate boost before the wastegate "sees" wastegate boost (ie you'll have a 7psi wastegate, but at 12 psi the solenoid will be bleeding off pressure so. Symptoms: • Broken parts due to excessive line pressure • Erratic line pressure • Harsh shifts • High line pressure • Restricted converter/lube flow • Soft shifts 95740-78K Oversized Pressure Regulator Valve Kit: • Hard-coat anodized aluminum valve combats premature wear • Sleeve manufactured from highly wear-resistant aluminum 53 of 72 Pressure Regulator Gen.
