and a Kennedy diesel boost valve that doesn't do anything
:rolleyes:

Well, he was serious. I received the KD boost valve in like new condition. Thanks Linchhummmer.
I put it through a rigorous and thorough test. It worked perfectly, as advertised. Details of my test procedure and results are available upon request. The end result was very pleasing, and surprising. My boost gage goes up to 30 PSI, and with the valve at full adjustment, the boost was rocketing past that in a hurry. However, at stock fuel levels, there was almost no discernible gains I could tell. Perhaps a little, but it could easily have been within a margin of error, and due to changing conditions. Adding fuel was the key, and had profound results. An added benefit was, as the boost climbed quicker, EGT's climbed slower. A very nice side effect.
Although this little, unimpressive looking device is quite expensive for what it appears to be, it delivers in a big way. It's probably one of the best investments a you can make, if your goal is to increase available boost, beyond what your fueling programmer or box provides. I would have had one long ago, if I wasn't turned off by the price and appearance. Had I known then what I know now..........
The combination of JK's tune on my 2002 LB7 and the boost valve have produced the best overall towing mileage numbers of all 5 Duramax powered trucks I've owned. 275K miles of daily towing and winter snow plowing - under 1500 miles per year (up to deer camp and south to pheasant hunt) unhooked from the trailer. The combo simply rocks, and saves $$$ each tankful.
It takes more fueling to see the boost valve function propertly. It was very valuable in tuning diesel/propane/air mixtures on my previous 2001 - where 28-32psi nominal under fully loaded towing was commonplace...:eek:...with only 1200 peak egts, 900-1000 nominal.
That truck would pull 12K# of boat and trailer straight up, if you could find a road that steep... :)
Thanks for the heads up. Unfortunately, he'll probably keep the negativity in his signature...
Just disappointed that someone would publicly condemn a fully functional (and mfr inspected/tested) product without testing on another vehicle.
Oh well, Dmax Mav got a heck of a deal...
Just goes to prove you can please some of the people, all of the time. You can please All of the people some of the time, but you can't please all of the people all of the time.
