I'm looking at getting a kit from 935 that will put me around 400 WHP. Question is, should I upgrade certain parts? The FMIC setup I'll be getting is 24x12x3 and has 2.5" piping. Will this be enough or should I go 3" piping? Also, Will 440cc JDM (cleaned and flow tested) injectors be enough to handle this, or should I upgrade them to 520cc injectors? I have a full 3" catless exhaust, cold air intake, SAFC Neo, and the Aeromotive FPR. :1zhelp:
