Hi everyone!, I´m having a very weird issue. At wot, car starts fine but when turbo spools low fuel pressure starts dropping, high fuel pressure drops also (can´t say wich one makes the other one to drop), and car starts to have lean conditions and missfiring badly at around 5,800rpms...
Parts already Changed:
Low fuel Pressure Pump
Module that has on top of it.
HPFP Cam Follower was pretty bad so changed for a new one.
New Spark Plugs BKR7
