    Wow, that coolant return from the turbo is... interesting.

    IIRC one of the imgur.com link options should do all that for you..I think the "BBCODE/Forum" one or something



    here you go:

    Thanks for helping post it. I had to put the space in it because of a 404 code here

    I didn't do most of this so be blunt and brutal. I figure that I know a sliver about this car compared to you guys and I'm taking every bit of advise very seriously. Point out the flaws seen and pick it apart. I'm tired of it running more like a turd than a car.

    Doesn't look like there is a vacuum line going to the fuel pressure regulator, unless I am seeing it wrong? That will cause the fuel pressure to be 10psi high at idle (about 20%). Combine that with bigger injectors on a stock calibration and it could add up to the massive overfueling you are seeing at idle.

    Looks like you have something tee'd off the fuel pressure test port and going inside the car. Is that an in-cab fuel pressure gauge? What does it read at idle?

    Dont push the red button.You hear me?

    There is a vac line hooked up to it (the fitting on the regulator is loose though) and, yes, that's a fuel pressure gauge. It reads about 25 to 30 psi at idle. What should it be set at?

    At idle assuming 18" of vac you should be getting about 46PSI give or take.

    If the injectors are near the stock size i would run the stock fuel pressure. 55psi with the engine off.
