Back to original question....

Cars with an air mass flow meter, like ERST, will not tolerate uncontrolled air in/out leakages through the dump valve because this will mess up the fuelling. Soft single piston ones tend to be a bit open at low throttle and thus cause air to be sucked in and leaning the fuelling resulting in bogging. Cars with MAP based fuelling don't really care too much, and practically any dump valve can be used.
