Had to re fit the wilbro fuel pump as my spare stock was giving up think its coz the ecu is maxing them or there just old.
Anyways gone back to wilbro which over rides the stock fpr so had to fit adjustable on went a bit mad as went for the 400+ as i cant be assed to change it in a years time when td04s go on anyways. Im not 100% when it comes to fpr ive put some in but its always been setup and mapped without me turning a key.
Anyways its on its adjusted to 38-40 psi no vacuum but when i add the vacuum the pressure on idle dosnt drop all though nore dose the pressure drop off when you blip the throttle like it use to so to summarise.
Wilbro pump, d1 spec 450 fpr same as tommi and sard, set to 38-40psi but no drop at vacuum. Should i worry?
