i just put a turbo kit in our stk 2003 celica gt with a 1zz-fe motor with a auto trans the turbo installed is a garrett gt28rs and we added a aem fic/basemap along with it and also 440cc injectors also the exhaust has no cat in it and is free flowing know hers my question after install we took it to a experianced tuner with a dyno and are have a problem with the fis being tunable he's recommending that we try to fine a stand alone ecu to accomadate the new upgrade with a extra injector for thr tuning ease any help with this would be great i tried apexi but the system doesn't support auto tranny it seems to wrk better with the stk injectors in it and with the aem fic disconnected
