there is no english apexi info really available on the net or through apexi for that matter unless u r an apexi power excel dealer. but a friendly guy at apexi helped me out once and pointed me to
this page. it's a jap page but translated in the link by babelfish. goto TOP FRAME electronics -> LEFT FRAME each part data -> LEFT FRAME top or side feed to get to the injector info. its a great resource with flow rates and lag times at different pressures.
HTH.
