I have Needswings dual CAI, Needswings manifolds, Needswings Y pipe, 178 crank pulley, Needswings pulley saver kit, cleaned and serviced blue injectors, slightly ported throttle body, long tube headers, EC 96 tune, (runs fine on 93, some 96 tune...) wide band with Zietronix and Dashdaq. Other stuff in my signature. When I started to lean out my solution was a Pierburg fuel pump purchased from Needswings. I didn't change the filter or instal the fuel pressure regulator. I don't go lean.
