Hello I have a mk4 Jetta tdi with the Bew engine.
I have done a vnt17 turbo, fast road cam from dark side, and kerma pdi 150 injectors. It is tuned though Malone. I have an idle drop issue went coming to a stop. It drops below specs and then after siting on idle or pressing the accelerator pedal is comes back up and then siting at 903rpms. also has a rough start. I am wondering what i should check or what might be the issue.
