Yep, as Willtel suggested your "clicking" noise is the boost recirculation valve internal piston bottoming out on worn rubber gaskets that ordinarily provide some cushioning effect. It moves in response to engine vacuum, so when you're suddenly on the gas or off the gas, the piston will move. Fix it when you have the time but meanwhile do not worry about it. It will not cause any problems unless the gaskets are so worn that they begin to leak - which would cause poor running conditions.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
