what do you plan to do with it. the simple answer is "it can..." but there are too many factors. its usually a good idea to keep your base fuel pressure where its supposed to be and most people just buy an afpr when they get a fuel pump that is so big that they need a stronger fpr to keep it under control. if you arent tuning (SAFC, etc) id say skip it.

I have a 97 eclipse gst, the two injector on the passenger side don't seem to work, there is still power but it's not getting a pulse from the ecu

what do you mean the best way? you hit fuel cut when your ecu sees enough airflow to think that its approaching 100% duty cycle on stock injectors. pretty common on modded dsms around 16-18psi. thats when you get bigger injectors and lean them out with an safc. it tricks the ecu into seeing less airflow and delays fuel cut until you make up all that extra airflow with running more boost.

I wouldnt say safc alone. If you lean the safc out with stock injectors you will blow your motor. SAFC, bigger injectors, and a dataloger of some sort is what you need to do it right.

just get a maf translator- no more fuel cut. plus you get the extra little goddies like, easy tunning. hp increase. and the one that everybody loves you can vent your bov with out side affects.
