Stock Injectors

[Alpha D]

Also for you gus with all the tuning software and know how to self tune or dyno tune, its not often almost ever I hear of fuel pressure being increased to get more flow out of an injector once its reached max duty cycle or w/e maxxed out injector means...how do you figure out what is to much pressure for an injector? because for example: If i just buy a set of injectors... the company dosnt know what pressure my car runs....Is there a standard or so? Never bought brand new injectors (i assume the instructions would shed light on that?)

In school we learned that most modeen vehicles have like a min of i think it was 60psi...its been to long i do not remember the generalized psi spec that was given..however the point is there was a standard which most new cars hovered around..

I know direct injection cars like the newer cobalts run a much higher base fuel pressure, granted the injector design might be different and cant be exchanged ...with a dsm injector clip..or that of a toyota..... So lets just say... hypothetically speaking they could fit...wouldnt yu get a different cc rating or fuel flow? lol if you purchased a aftermarket injector
