When I install new (bigger) fuel injectors in my car will I need to re-tune the V-AFC to handle the new fuel amount, or just use a FPR to set the pressure. My current setup is all in a 00 Si--Toda spec b cams/gears/belt/springs/p-28/vafc/jdm header/CAI/test pipe/dc exhaust. The guy at the dyno recomended stepping up to some 310 injectors. I was thinking of just running some s2000 injectors. Any thoughts and comments are welcome. Thanks
