youre getting boost cut...and you want to get rid of it...but now ur getting the boost cut defender...doesnt make sense...maybe im reading it wrong... the boost cut defender acts like a wastegate...too much boost and it cuts it off...it bleeds the boost and no more of it enters teh combustion chamber until the boost level drops....

hmmm, his question was what kind to get??? and actually the AFM is sensing overboost and it tells the ECU to shut off the fuel for a second to prevent damage to the engine from occuring untill normal boost is sensed again.. Get the hks fuel cut defender type k3 i believe. needs the kind for AFM's and the extra rpm signal wire.
heres hks site. check the part # and give it to this ebay seller for $99
