ive searched and searched and my car still makes the cha cha cha noise. i have the knockoff greddy rs and i took out the bigger spring(didnt help) i had it t'd off a line on the intake manifold(also had a boost gauge connected there so i decided 2 t's on one line was too much) so i disconnected my cruise control and connected it there and switched to bigger line nothing has helped....any ideas? is the cruise control vacuum source not strong enough?
