    Answers to above questions:

    Check the fuel pump and measure fuel pressure: Completed and within specs


    Have you checked the blower or as some people call it the supercharger? Yes and Replaced


    Are the injectors 9a-90, if so is it giving the 475 horse power? That’s stock for that engine. But don't know about that year engine to be exact? What’s the horse power or did I miss it? 9A90 are mechanical engine injectors, 400 hp 1.460 in timing tool per DDC Bible specs Injector is 5234770

    The uneven exhaust temp is pretty crucial. What have you ruled out so far? Injectors have been replaced w/ DDC remans and also have been pop tested for spray pattern and flow.

    Is it chugging uphill or just bad power, did this just happen out of nowhere? From what we can tell just extreme low power. I have not experienced any chugging.
