only way an actuator can improve "lag" if you want to call it that is by holding it shut till full boost, and even a 30quid dawes device will do that for you
even better when ya remove the actuator pipe
the 30 quid dawes device works very very good steve i shit you not
, there not goot a big boost aplications but are ok upto 30psi
down side is they seem to make the boost come in with a bang
, thats not good in thw wet and rwd
, there very good systems though , very underated imo
