BMW B58 DAW Flowmax+ 'Stage 3' Tuning Package


To make it easier we have put together a 'stage 3' tuning package for the BMW B58 engine, found in the M140i/M240i/340i/440i etc model cars.

This package is based around the Dynamix Autowerx Flow max+ turbo.

As part of this package we also include a custom ECU tune via Odin Tuned, this will be done via Bootmod3/MG Flasher/MHD.

The downpipe we use for this is either the VRSF catless or catted downpipes, these are both 4.5" diameter and offer very good fit and quality at a very competitive price.

We offer three different options of high pressure fuel pump:

B58TU - at its limit at about 580hp on UK 99ron fuel, limited in ethanol content it is able to flow.

Dorch stage 1 - offers more flow than the B58TU, will make similar peak HP but will offer more mid range power than the TU hpfp.

Dorch stage 2 - this pump is ideal if you plan on using stronger ethanol mixes, able to flow much more fuel than both the TU and Dorch st1 pumps.

This is for a complete drive in drive out package from a standard B58 to a stage 3 monster! If you have already fitted some of these parts we can remove and discount them from the cost.
