    History is as follows:

    Owner has owned bus (Bluebird Wanderlodge motorhome) since 1999 and notes it was never particularly well-powered. Motorhome weighs ~42,000lbs and would tow ~9,000lbs car and go up Interstate 80 and 81 hills at ~20mph – but this has since worsened…

    Bus was stored for approximately 5 years without being driven. Work began approximately two years ago when bus was noted by mechanics as more severely underpowered.

    Fuel tank and lines were replaced, as were injectors. Turbo and blower were reported as changed. Road acceleration remains extremely poor.

    At this time:
    1. Fuel Pressure checks – good.
    2. No diag codes noted.
    3. Battery voltage – checked / corrected.
    4. Exhaust system: leaks addressed correctly, changed the muffler to a resonator, turbo pipe and exhaust manifold replaced.
    5. Exhaust temperature = erratic / cold. Injectors rechecked and they were rechecked as ok.
    6. Stall test (holding brake) only pulling 900 rpms at full throttle.
    7. Throttle up in Neutral (no load) is good.
    8. Free run on dyno: (no load) limited to 53 mph!
    9. Transmission function appears correct.
    10. No excessive white, grey or blue or black smoke.
    11. Compression tests normal
    Many different avenues have been dead ends in solving the low power issue and the shop is considering ordering a replacement EDU (cost > $2000 plus labor) with the guess that that may be responsible for incorrect firing of injectors.

    Any ideas on other possible causes before replacing the EDU?

    Also, does anyone have any leads on obtaining DDEC 1 EDU PN# R1227328 (Needed for 8V92 08vf120945)

    Thanks for ideas – and leads!

    Steve

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

    So it was on the dyno. How much was it putting to the wheels?

    Are the injectors 9a-90, if so is it giving the 475 horse power? Thats stock for that engine. But don't know about that year engine to be exact? Whats the horse power or did I miss it?
    The uneven exhaust temp is pretty crucial. What have you ruled out so far?
    Is it chugging up hill or just bad power, did this just happen out of no where?

    You seem to know those Jimmys. What kind of reliable horsepower can you get out of one.

    Would like to put one in my HotRod boat to be different.

    Lol I don't know anything about them. But there the same engines as a small yaut ( rich mans boat, if I spelt it incorrectly) I was working at a parts warehouse in concord n.h back in 04. And it seemed like every other Friday the same old man came in looking for these injectors for his bosses boat. I think he said they also have 6 8 12 cylinder engines.
    That's why I expressed above I don't know anything about that year. But I love all things mechanical. And hope to learn from this persons experiance.

    Ok yea. Most yachts with old Jimmys were sent to the chopping block because of their in efficiency and no one could possibly afford to add that much oil every boat ride.

    I wanta piss off the greenies with my hot rod , being my built sbc with open stainless headers is not offensive enough.

    Now a Smokin Growlin 8-92 with Zoomies would do the job I think.

    Make sure it spits flames and burns four gallons to the mile

    And drips a quart an hour .

    A 12 cylinder would be fun but would have to mount it midship to keep from sinking.

    You sure that's not a Harley engine in your boat?
