awesome info..... the only thing is..... real oem shows a completely different fuel pump for the z4m compared to the e46..... however i agree with you that it surely must be an equivilant?? im wondering where Ess got their data that it cant supply the fuel needed..... Anyhow ;-) i'll update when they get back to me ;-)
