The mechanic at Godzilla Workshop found out that the fuel pump relay is not installed properly. That might be the reason that causes the fuel pump to work irregularly. My car has been stalling non stop like it was out of fuel, but after he has sorted it out this problem has been fixed.
So the fuel pressure regulator has been readjusted to optimum level which is 2.8 bar over...
Since it's getting enough fuel, the next things to check is the spark plugs, even though the previous mechanic has checked before and said there are no issues, well who knows this mechanic might find out different case.
Coils are also needed to be checked even though all are replaced with NEO coilpacks which I have mentioned in my previous article. Well basically it's running a full inspection of every possible causes such as Spark plugs, coilpacks, fuel pressure regulator, fuel filter, fuel pump, fuel pump relay, boost controller, minor leakage, ecu tuning, oh and MAF Sensor (checked already, no issue)
Hopefully the workmanship isn't going to cost a lot because there are just too many factors that causes my engine to be spitting or mini misfire especially on high boost, 1 bar maximum.
