I had purchased a brand new standard boost adjustable actuator, I cant get my boost lower than 17-18lbs, I thought I might have gotten a high boost actuator by mistake but the vendor insured me that was impossible.Has anyone ever had this problem,I want to start to tune my car at a lower boost level and work my way up.I am all ready getting knock with the rod on the actuator adjusted all the way out.Any info would be greatly appreciated.Thanks,ikle.
