When tuning BMW’s B58 engine (as found in the F2X M140i/M240i, F3X 340i/440i and more) one of the biggest restricting factors is the factory fuel pump. However thankfully, when BMW unveiled the B58TU (technical update) it came with a higher capacity fuel pump which is relatively simple to retrofit to the earlier B58 engines.Usually the wiring connector on the TU pump faces the wrong way and so requires extending of the wiring loom. However, we reconfigure these to make this pump an absolutely direct swap for the original.

The increase in fuel flow allows for nearly 600bhp on pump fuel with a suitable turbo, and is also perfect for running methanol blends where a larger quantity of fuel is required. This is a plug and play upgrade but will require tuning to gain full advantage.
