INSTALLING THE VALVE Note that installing the Respons T9007 must be done from underneath the car, which requires raising the car on ramps or axle supports, or a hoist. WARNING: NEVER work under a car supported only with a jack. 1) Remove the plastic section of the under tray by popping the plastic clips and the two bolts. Note that there are more plastic clips than indicated by the arrows. Diverter valve location 2) Remove the two hoses from in front of the diverter to gain access to the clamps behind.
Adjusting the sPRING PRELOAD Contrary to popular belief, the spring pre-load DOES NOT need to be adjusted to suit different boost pressure. The Respons TMS will stay shut under full throttle conditions regardless of boost pressure or spring pre-load. Rather, the spring pre-load affects how easily the valve opens when you lift the throttle, and how long it stays open when it vents.
Adjusting the sound The unique patented venting bias adjustment feature on the GFB Respons lets you vary the amount of air vented to Venting bias adjuster atmosphere or recirc, thereby changing the volume of the sound. Turning the venting bias adjuster anticlockwise will open up the trumpet outlet more, making the valve louder, whilst clockwise will open up more of the recirc outlet for quiet operation.
