So just went to get a warrant, apparently now EBC's require certification as of June 2012 according to the inspector. Rang up a guy in Papakura who does LVV certification and he hadn't heard of it but after looking it up apparently the original inspector is correct.
Seeing as that's my only modification I will be switching back to the factory solenoid and system as $520 for a cert isn't worth it on a daily driver for me.
Any comments or advice welcome
