Controlling a stock ct9 is a challenge for most ebcs, mbcs are pointless on a ct9, tried and tested boost creeps like a bitch so you have to set it low and let it creep to your desired boost. It works this way but you loose the low down kick of a ct9 which is the only point running a ct9 imo. I'm using a gizmo ebcs and even then it'd not perfect, have to set it lower and let it creep still but only by .1 bar. Before I ran. aboost controller I just set boost off my actuator. It performed same as my mbc so why not just set boost off 6our actuator for now?
