Hey guys i just bought my first wrx a few days ago its a 1996 impreza. Its running a gfb manual boost controller but im pretty sure its all plugged in wrong as the car is only running 0.5 bar which i believe is waste gate pressure? So i was looking for a way to start using the stock boost controller again but ive been told its not as simply as plugging the lines back in because it needs restrictor pills or something.
So does anyone know how i can revert back to the stock boost controller or if there is any other way i can just get back to stock boost which i believe should be 0.9bar? I was hoping to not use the manual boost control as people have said their not very reliable.
Thanks

bump

Have you tried speaking to any of the workshops?
