Is it possible to run FSI/TFSI with return-style fuel or is LPFP pwm absolutely necessary?
Im running with return on my VR6 3.2 BUB and turbo.. Ive been tweking with FKKVS.. 4bar Bosch FPR.. Using modded tank ventilation pipe as return. Fuelpump system need to rebuild. Im not sure about TFSI though
