Man i told you that you got the wrong pump, the pump you got are for turbo ready cars like the gst, gsx , evos, etc about 90% of the board members that are turboed 420A use the 255 High Preassured Wallbro. it might be your problem using the 190 espeacially with preassures around 85psi not really sure i doubt it though. i think it has to do with your map. I know you have a small t3 and it spools up real fast but i think it has to do with something else. check all your connectors even check you'r camshaft positioning sensor make sure all your connectors are good. does your car drive normally without going into boost? if it does drive normally than is the wastegate acting up. when you say cutting fuel do you mean it cuts the car off and jerks. a map sensor seeing boost may cause this not all 95 and 96 420A need or not need a missing link but having a missing link is insurance. clean out the missing link? get a volt meeter and check if your map is seeing boost have someone rev it and check the voltage. i think the map cuts boost at 5 volts your turbo is pretty small so i think you can rev it and get at least 1 lb of boost by reving it. did you re solder the wire when you took the voltage clamp off if you didn't you need too?
