is your mate brett,scott,garth ,warren or alan?
before you ask questions on here how about going back to shop in question (if it was fitted there on the books) and explain you are not happy. yes I know who you are referring to and the shop in question. have seen a gry R34 sitting outside that shop a few times now. if that is you then I know the car in question. regarding the focal items: they DO need break in time.
as for the immobiliser - no idea. could tell you more if I saw it.
