i't more for tuning than brake booster, thats just the bonus.. if you can get your hand around the back to adjust and tune each of the throttle bodies to read the same vaccum on idle please let me know.. i found it impossible as the T3 manifold mounts the TB's upside down..and the screws face the engine.. i did this so i could tune them by eye off the car, put them on and not have to really worry about one leaning out and melting a piston cos it doesn't read the same as all the rest..
put it this way the MAP and dizzy block averages out the fuel needed right, but a 3mm vac line won't do shit to average the vaccum between cylinders..thats the key![]()
