hey guys, got a s1 stagea gt35r turbp front mount haltech comp full exhaust injectors, pretty much the lot, also have a turbosmart 2 stage bosst controller, it is turned all the way down on both, but the car seems to run max boost, then boost cut stops it, its really frustrating me, an it only be a whole in a vac line? can there by any other ways boost can spike? shed some light on my situation, cheers...
