Not a lot, and if you're not doing headwork (port/polish), then it's really a waste of time/$.
Do we know the standard duty cyle of our injectors? Is there much ceiling? Maybe you'd have to upgrade if you did headwork and big bore TBs?
On the S54, we're finding that the stock injectors are pretty maxxed out after you do the standard bolt-ons (catless headers, cams, airbox, tune).
