If you look at my initial post, i did mention i want to tune the hks adjustable to stock settings as i have a bad actuator hence i am asking these questions. Sorry if 14psi is not 1bar. I just round the figure up. So it's confirmed, Hks actuator is factory preset at 14psi minimum hence i cannot use it on a stock turbo as i cannot tune it below 14psi. I was hoping to get it down to like 7psi or so.
