I done a search for this and didnt find what I was looking for, so either its not here, or Im blind

Question is, Im trying to decide on to decap my injectors or buy 2nd hand STi injectors for my car (Ill be installing a VF43 turbo & TMIC upgraded of course) into a MY02 WRX

With the decaps, does that change the amount of fuel used while the car is cruising as opposed to how much putting the STi injectors would while cruising?

So, basically, would there be any fuel usage difference between decaps and STi injectors if they had the same mods done on the car? (tuned of course)

Im leaning towards decaps at the moment, unless someone has some tragic stories to tell (was going to get ASG to decap them)
