    Used truck market at standstill??

    Of course that's true, but most folks don't need that. Modern gas trucks easily handle 8k-9k. Since that's more than the vast majority will ever tow, why bother with the extra upfront cost and maintenance nightmare dealing with the EPA BS? That general sentiment is substantially more...

    Used truck market at standstill??

    Yea, the sky definitely isn't falling, and things are still pretty hot for sure (especially compared to pre-2020). Just saying that, for the first time in several years, prices are noticeably declining on used cars and discretionary 'toys'. Because I'm a nerd, I just took a look at the...

    Used truck market at standstill??

    It's not just used diesel trucks. It's pretty much everything. Older Japanese econobox cars that were quickly fetching $8k-$10k a couple years ago, are now sitting for weeks at $5k-$6k. I've seen prices on older, limited production Camaros, Mustangs, etc. fall from $40k+ selling instantly...

    sac45 idle

    My S&S SAC45s don't seem anywhere near as bad as yours seem to be. I've never once smelled them in the cab, even with the windows down. Around the back of the truck, you can definitely smell them, but it's relatively tolerable, IMO. I'll catch a slight, but noticeable, haze in the car...

    sac45 idle

    Sorry, I made this confusing by overtaking vmyrhaug's post. He's the OP, has the 4-year old injectors from LDS. I have 4-month old injectors from S&S / bdsankey. I'll bow out now, apologies. LLY pilot timing tables made a substantial difference in cruising fuel mileage for me, and a small...

    sac45 idle

    Mine are brand new S&S, bought through Brad about 4 months ago. They're completely perfect otherwise. Great balance rates, run completely perfect and clean at WOT, getting fantastic fuel mileage (as good or better than the stock VCOs, though not until I switched to an LLY pilot timing...

    sac45 idle

    Why would it smoke at -4? -4 is the stock timing in my OS. It has a very slight haze and smell (can only see it at night with a light), but definitely isn't heavily smoking. Main mm3 is 7.5, and all balance rates are +/- 1.5. I shut off each cylinder individually and the smoke output never...

    sac45 idle

    I recently tuned my own S&S 45% SACs (though life got in the way and I never got it fully finished). I also have a very slight haze and smell at idle. I did some testing with fuel pressure and timing. I found that they made no difference at all. Had -4 degrees and 35 MPa in tune 1, all the...

    LBZ tuning criticism

    I'll preface this with the comment that my situation with tweaking the pilot timing is a bit unique. I replaced my stock injectors with 45% over SAC-style injectors, which are both larger and have a different style nozzle from the stock LB7 ones, so a pretty drastic total change from stock. I...

    lb7 "stutter" under acceleration.

    This may sound a bit crazy, but check your transfer case. My truck did the same thing (a random, single buck / stutter only at light-medium load at cruising speeds). Was perfectly fine at <50 mph, and when under load. The tensioner had worn through and the chain was slack / slipping.

    LBZ tuning criticism

    I know exactly what you're talking about regarding the advice and opinions you'll find on the web regarding diesel tuning. I've been getting back into tuning my truck a lot the last 6 months or so, and I've come across plenty of good and bad advice. With regards to fuel mileage tuning, some...

    Lift pump sensor

    Sounds hokey, and I did have to make a custom receiver bracket for it, but I used an old Ford fuel rail pressure sensor. I got it from a pick-and-pull junkyard for like $5. They're on virtually every Ford V8 made since 2000. Been working perfect since ~2016. I found the 0-5v scaling...

    Head gasket build

    Dang. At least you felt it and stopped turning before snapping it completely off. Also, you just reminded me of a mistake I made when installing those. So with the crush washer for those (the one going to the head), make sure the little connector tab that joins the top and bottom washers...

    can someone bring me up to speed on tuning?

    A bit of a contrary opinion on a forum with 'diesel' in its name, but have you considered just getting a gas truck? If you're towing heavy a lot, then the diesel still probably makes sense, but the newer gas engines are lightyears better than the ones of the mid 00s. More than sufficient for...

    Head gasket build

    As mentioned above, it's part of the PCV system. There's a little chamber with a baffle built into the large aluminum alternator bracket. Any positive crankcase pressure is routed down into this box and then out the vent tube in the bottom of the bracket (vents right next to the crank pulley...
