First drain 2500 miles, roughly a tablespoon of oil. Fairly clean oil at that.

Mine definitely comes on all the time on dry perfect roads at nowhere near hard acceleration. So either yours is broke, or mine is. I know what the GM system is like without the Torsen, and it doesn't fight turning. To me this has to be the Torsen given that it tries to send power to the...

Here's what I know about a similar system in GM trucks. (I'm pretty sure our setup is them same, but don't shoot me if it isn't.) There's an axle disconnect in the front diff that is disconnected in 2H. When you put in 4A it connects the axle which increases the drag in the front diff which...

Pretty sure weather mode puts it in 4A.

Instead of a jumper wire you could wire it to another switch and then you could actually have control of it again. (Except for when the computer disables it.)

Use Forscan. It's a "hack" but easily undone.

Then don't use it. :) It definitely does "kick in" when needed, but it has an algorithm it follows to figure out how much power if any to send up front. One of those inputs has got to be wheel spin you would think.

Because it's in 4A. It's doing what it is supposed to do. Like I said, it's somewhat similar to AWD and totally normal to be sending power to the front, even when dry.

It's not touchy at all. You won't even notice it if the wheels are straight, or you aren't accelerating, or you don't have the Torsen. You really have to look at the Power Distribution screen to see what it's doing. I've been up the Eisenhower in a blizzard using 4A, the technology works...

The good news is that you aren't forced to use it. Plain ol' 4x4 is still there and it's locked so it doesn't rely on the clutch holding. It's a nice system when conditions are variable. You can leave it 4A forever if you want, you'll just potentially wear out the clutch sooner.

I thought you knew everything about 4x4 because you live in Colorado :) , but yes it does. 4A uses a computer controlled clutch to vary output to the front anywhere from 0-50% of power. 4H is part time (locked) 4WD split 50-50 front-rear My 2015 Silverado had the same thing, as did my...

A magical device called a clutch.

Thanks, mom.

4A is similar to AWD. If you turn on the power distribution screen you can see how it varies the output to the front wheels much like an unlocked center diff would.

No, I am using 4A in slippery conditions. It's fine, it's just annoying.

I've decided I don't like the Torsen diff. I hate how it fights me when I'm turning. It's probably great in 4-low crawling up something, but not in 4A.

The sound is what it is.

If you drive one like you stole it, I guarantee you won't give a damn about what it sounds like. I don't. Of course if a better engine comes out then I might be tempted to upgrade, but I'm happy with what I got now.

I'm waiting for the 2021 Supercharged 7.0L DOHC V8 that makes 1000HP!

There are 3 in my town of 50k that I know of. I see one dropping his kids off at my kids' school although I'm never in my raptor when I see him.

What's the difference between our EBHO and the GT's EBHO?

Sign me up.

My Raptor is my first forced induction engine. I don't think I'm ever going back to naturally aspirated anything.

Ok, hoses swapped. Engine cover is back on. All is good. I apologize to UPR. :) I have about 100 miles on the catch can so I figured while I was in there messing with it that I would open the valve and see what came out. Nothing. Absolutely nothing.
