My modified st is dropping fuel pressure, seems to be happening high up the revs, it possibly started happening around 6000rpm, then possibly getting worse around 5000rpm. Injectors have been checked, all okay. Would this likely be down to one of the fuel pumps? If so which one is it more likely to be.
just trying to make it a little easier for me and the tuner, before he gets it back in to look at.
