Here you go if you didn't get one already Here's a link. This website says the file is too big https://mega.nz/file/AqM0zZhD#Y8w_dSvot4JGm-Q5KOieDw5gZSqXexTEMhdYCZ86z34

These trucks are a little pricey to do, but 100% worth it in my opinion. You will see an improvement in mileage, and power increase depends on what tune(s) you buy. These trucks can make some serious power with tuning, but keep in mind, any increase in power puts more load on the entire...

You need to scan the TCM for codes. Sounds like the Bully Dog is only reading the ECM. Some of the fancier code readers will do it, or if you can, borrow a full function scan tool.

There are several stock tunes in the resources library on this site. If you just want a comparison tune, they should be close enough. If you want an exactly correct tune for your truck, post your VIN.

Glad you got it fixed. I'll have to add this bit of information to my mental files LOL. I didn't know for sure that the transfer case could cause the Range Shift Inhibited message.

Pretty sure the noise you're hearing is the park pawl grinding, because the transmission is still spinning. It sounds like your transfer case is still stuck in neutral. That might also cause the Range Shift Inhibited message, not sure about that. You should be able to remove the transfer case...

I would second adding a lift pump, but the good ones are expensive. You could maybe buy a universal 12 V pump and pressurize the fuel system temporarily to pinpoint the leak.

For what it's worth, I haven't seen a Michelin LTX that didn't wear the outer tread prematurely. Seems like a chronic problem with that tire.

A few thoughts I have: Cold diesels will emit some smoke/steam. It's hard to tell from the video how quickly the smoke evaporates. If it evaporates quickly, I would consider it steam rather than smoke. The LBZ has an intake heater. If that's not working it could affect smoke output. Although I...

Those balance rates are really good. Do you know if they were taken with the truck warmed up?

You're probably thinking of the LB7. They used a metal return line and had a passage through the head. The LLY and newer engines have rubber lines. Each bank of injectors is teed together. See the image below.

Could be a return line leak. The return lines are small rubber hoses with plastic fittings that push into the top of the injectors. IOW, not designed to handle any significant pressure or volume. If the injectors were returning a large amount of fuel, as yours were, the returns line(s) may have...

The pressure regulator is on the CP3, which is directly under the Tstat housing. You may have pinched a wire. I did that the first time I did mine, only the coolant temperature sensor wires were the victim.

So it's an autocal. I would still try to read out the stock tunes. Sometimes when a tuner sets up an autocal, they will allow it to read and "self sign" tunes, as if they were supplied from the master Flashscan. If your Autocal was never linked to a Flashscan, though, I don't think you'll be...

If what you have is a Flashscan, you can just download the V7.5 or V8 editor directly from Efilive's website, and edit your tunes. If you have an Autocal, you may need to get that unlinked from your old tuner, and relinked to a different Flashscan before you can use it.
