Hi guys! Can any help me I was thinking of getting the lastest hks electric boost controller for my gc8 im running a tomei arms 8265 turbo under the hood.

Im kind of confused with the boost solenoid and what its role is! If I get the hks ebc do I need to the upgrade my turbo boost solenoid aswell? Or does the hks ebc have a boost solenoid built in? I want to be able control the boost levels safely and not kill my engine....the previous owner use a manual boost controller and a boost solenoid with the stock turbo but since ive upgraded the turbo, im thinking I need to get a ebc..so can anybody tell what I need to do ? Do I have to get a aftermarket boost solenoid with the hks electric boost controller aswell? Or just get the hks ebc on its own? And does the hks ebc make my rexy perform better than the manual boost controller?
