    Hard to turn left.

    Installed a new steering box and power steering pump on my 2011 CHU and it seems to be stiff when I turn left compared to turn right. Someone told me it needs to be adjusted but I’ve never done that before.

    S400 Turbo too big for 1991 E7-350????

    2003 427, if you stay with the stage 2 you will be fine. Mine preforms best around 1400-1600 rpm

    (S400) # 23504966. I put stage 2 injectors and mine runs like a different truck. I tried stage 3 but was to much heated up to quick.

    I’ve got a s400 for a 60 series Detroit on my E7 with stage 2 injectors. Does great.
  13. 2009 CHU MP8 starts and idles fine, even revs good. When you get it out on the road does great shifting through the low side but once you get to high side it’s like you lose throttle but it’s on the floor. Pulled code and showing engine fuel delivery pressure. I check valve on the front of the head and the plunger is moving freely. I also check fuel filter house bc I had one that was sucking air on the backside of primer but it seems to fine. Could it possibly be the cups? I looked in fuel tank to see if there were any bubbles coming out on the return and nothing.

    Injector problems

    2008 CHU MP8. Going through injectors like crazy. You can put a new one in and it might last 3 to 6 months. Could this be a wiring harness problem?

    8-9 code Solenoid Boost Voltage

    It was active, engine seemed to lost a lot of power. Have to drop gears pulling a empty log trailer that I never had to do before.
