Hey guys, just a quick question. When i go to stage two with my 04 sti will i need new fuel injectors? I was gonna get new ones anyway just wondering if when i went stage two i needed to do the injectors at the same time, and what kind of injectors should i get? Thanks in advance
Yes sir thats what i was asking. Cause i read somewhere that for stage 2 it would be a good idea to get a new fuel pump. So for stage 2 i wouldnt need either new injectors or fuel pump unless i upgraded the turbo?
Not exactly "stage 2" but my tuner did believe that the stock turbo is limited by the stock STi injectors. If you're getting a protune, you might consider it even with the VF39/43 still under the hood. Being fuel limited is a waste For a cobb AP stage 2 map do you need upgraded injectors? No. In fact, you can't use that map if you did.
