I would recommend replacing the fuel pump as early as a stage 2. We have seen a couple of Sti's that have maxed out the stock fuel pump with some of the stonger VF-39's. Having extra fuel on demand is always a great idea and as we all know our Subies are thirsty machines. Besides it is one of the least expensive & most important upgrades.
