No the fuel pressure, we were monitoring the fuel pressure it reached 200psi then dropped. There was one code that came up with was the air mass multiplication, which I've been told to believe means the mixture or fuel to air was not right. I went for an aggressive map with Jason, I believe I mentioned it to you on another thread. He is addiment that its the hpfp. He swears by his experience it wasn't a turbo pressure lose. I have hardly any experience in this field so I am following what I've been told. I see no reason not to trust his advice he was a great guy and was extremely helpful.
