Limits of factory fuel system?
So from what I'm reading most chipped cars are running around 18psi on the factory K03. At what point do I want to consider injectors and/or a FPR? I have not read much about replacing fuel pump so I"m assuming mine is good unless I go BT.
Chips such as the APR 1+ that add injectors and claim another 20+hp, I'm assuming they are just raising the boost to the 20-22psi level, which required more fuel than the factory injectors can deliver?
Still deciding between the chip route and the diode/MBC route.

RE: Limits of factory fuel system?
same answer as on audizine... get OEM tt225 386cc injectors from manguyen (PM him on audizine and tell him i sent u!) but definitely dont get stage 1... at least 1+ will pacify for a week maybe... honestly i would just do your supporting mods first ( clutch, suspension, brakes, FMIC then go APR 3+ or if you like to tinker go REVO BT (GTRS, gt28rs gt3071r)
our cars dont have a FPR, its internal to the filter
there are many guys with BTs and BAT, even 2.0 strokers on the OEM pump
