There are no upgrades anywhere for these direct injectors, however fueling isn't a problem since S63tu M5 are making over 820rwhp with meth.

The only problem with fueling is if you don't want to run meth. That's true on any BMW turbo motor. The N54 has aftermarket port injection setups but that's not coming to our motor any time soon if ever.

If you don't run meth on these motors your limited to less then 600 rwhp. That's the choices you have.
