The original post indicated they are working on an early '99 truck while the link TARM posted appears to show bearings for the '99.5+ trucks. I know there are differences in the front brakes but I've always wondered, can you convert the early '99 trucks to run the later, more common hubs? If so...

Put your late '99 ECU back in and put the chip on that. That should work.

Sent you a PM about the ECM, thanks.

Try contacting a local driveline shop. They should be able to fix you up.

Like the title says, I'm looking for a DPC-422 ECU. Let me know what you've got. Thanks!

That is not the only thing I'd be worried about. If you're worried about it why not call the manufacturer and see what they say? Don't you think you'd get a more accurate answer than you would on an Internet forum?

Do you really have any reason to question the integrity of the motor? In some cases you're best off just leaving it alone. If it were mine and it came out of a running truck I'd just put it in and see how it runs. FWIW, engines will run and make rated power even with differential compression...

I think I can count on one hand how many times I've done a CLT on a warm engine. We almost always do them cold. One word of warning - your leakage numbers will vary depending on how large the orifice is that is in the tester. I'd take the numbers with a grain of salt, they don't mean much in my...

Looks like a typical water brake dyno graph.

Firing pressure is relatively easy to measure on a diesel with glow plugs. If there are no glow plugs it gets a little trickier. The data acquisition equipment needed to measure firing pressure isn't cheap. I'd say it is out of range for most individuals and probably even a number of shops...

I guess I'm not real sure why you believe buying parts as a shop is any different than buying them as an individual? As an individual, I'd be looking for very similar qualities. When dealing with high performance aftermarket parts I don't worry a whole lot about warranty length, but more about...

You act surprised. That's how it's done in many places.

When we break engines in on the dyno they all get JD 10w30 break in oil and are run at light loads with varying speed to start with. The load is increased the longer the engine is run, and it will be making rated power within an hour or so. At that time the engine is considered broken in. The...
