Rich RDE Posted April 17, 2017 Report Share Posted April 17, 2017 Anyone have any experience with the fuel pump control method for the audi 2.0L direct injection setup using aftermarket HPFP's for these engines? According to the manufacture, the aftermarket pump is increasing the volume or bore size of the piston. The actual lobe does not change at all. I will be consulting the manufacture of the pump's here shortly to ask them some questions regarding this. Supposedly 50% increase?Any help would be great.
