    Schrader valve delete question

    I just removed mine. You don't need it except to diagnose if your lift pump is putting out the pressure you think. If you trust your lift pump or have other areas to test pressure, you can just remove that test port (GM calls it a Cold Start Valve) and all related plumbing. Mine has been...

    cab heater core

    I suspect it would be possible, but you'd have to verify hose diameter. I think they're a vestige of the shared platform with the Tahoe/Suburban, which has the rear heater lines T in at those fittings. That would let GM keep the hose length identical between the truck and SUV. Though I question...

    L5P L5P Tuning

    Some people want an altered shift strategy, not just a pressure mod. Depends on what you're looking for. Like why pay the $5-10k to tune a L5P when you can buy a used Corvette that'll be faster than a tune-only L5P? If you have to ask, it's not the product you're looking for. I don't personally...

    Enabling TPMS

    I have a 2003 with factory steering wheel controls. I reprogrammed the BCM to a 2004 and put in a 2006 Denali cluster. The Denali cluster may be the source of my issues, as it was weird even before I reprogrammed the BCM. The other stuff works (Trip A, Trip B, Avg. Econ, etc.), but no instant...

    Enabling TPMS

    That's excellent news. I do wonder if the pressure display comes from the cluster or the BCM? If you ever get access to a Tech2, I'd love for you to post up all the hardware and calibration IDs from the cluster, BCM, and PDM. My TPMS works but doesn't display pressures on my 2006 Denali cluster...

    truck towing pictures...

    I use it to push stuff around on the farm, but it would probably work great for that too :spit:

    truck towing pictures...

    Installed a gooseneck hitch last night and picked this up for my brother this morning. Never towed a gooseneck before, it's pretty sweet. Much nicer than a normal trailer.

    LB7: Help Pinpoint 1093 issue

    Sometimes scanners don't play as nice with the 2001-2002 trucks as later trucks. The early OSes were picky. Since the scanner doesn't want to work, just unplug the FPR. That will result in max pressure. If it can't hit 160 MPa at idle with it unplugged, you have a mechanical problem. Usually a...

    Ad2 165 o-ring kit?

    This is the point where you spend the $50 to get the 4G upgrade. :thumb: Because even though you got the quietest 1G motor ever, the new one probably won't be. Are there any part numbers on that seal? I couldn't see any in the photo. I doubt it is custom to their application. Might be nice to...

    Advice for initial start up after HD/ injectors

    They are the same sensor, you just need a MAP boot. I even gave you the part number earlier: This is not speculation or guesswork, I did this exact thing on my Suburban. I even provided a picture of the bracket to make to hold it in: If you don't believe me, go look up the part number on...

    Chevy1925 (James) Truck/motor build

    You lucked out, my friend. Once you get diesel in the motor, it combines with that graphite residue from the brushes and shorts everything out, then that's that. Plus the smell is indescribable :eek: I had to pull my lower oil pan once (a crappy 7mm socket popped off the ratchet while attaching...

    06 Tahoe body lbz chassis

    2500 Quadrasteer Suburban solves that :woott: Keep with the Tahoe if that's what the wife wants. A 2500 Tahoe will be one of a kind.

    Ad2 165 o-ring kit?

    When it rains it pours, right? I just went through all the little detail stuff on the Suburban, so it's fine so far, but my truck decided to open up a couple coolant leaks. Looks like both heater lines started weeping, my turbo thermostat delete plate welds started bubbling up coolant through...

    Ad2 165 o-ring kit?

    When my motor burned out and I swapped to the 4G, the seals didn't look like viton. I think most of them were normal cheap rubber O-rings, so if you have a seal assortment, you might be good to go. Going to viton shouldn't hurt anything, and isn't much more money. Are you sure it is one of the...

    2020 hd

    I do wish they'd stop making the beds so tall that you need a step to do anything, but if you're going to make it that tall, might as well have a step. Though even with a step, it restricts you to lighter stuff. I am able to grab 40-lb bags of ice-melt over my bed sides just fine, but trying...
