Right to continue from my other thread i was at Falkland performance on saturday and got it rolling roaded and logged on VAGCOM no faults and the fuel presssure was spot on too! Ive added autotech HPFP internals to my spec and as such it hasnt helped obviously.
Pictures of dyno graph below as you can see it looks spot on until 4500 ish then boom it dies off and tries to recover but just cant this only happens in 4th 5th and 6th and since ive installed stage 2 bluefin.
Anyone have any ideas Kev had me in the car on the rollers keeping an eye on fuel pressures on VAGCOM whilst he dynoed at and the pressure was holding spot on. Only thing we did notice was the reading for the fuel pressure regulator dropped to 0 when it hits the flat spot then it starts to rise again when the car picks up again.
