Loss of power and lots of black smoke!!

Check the turbo wastegate, make sure it is not hanging open for some reason.

Other things that will cause this are.....

• Warmup Valve stuck closed
• Leaking exhaust up pipes
• Boost leaks
• Turbo failure

There are a few more things that will cause this, but these are the most common issues.

Good Luck!

My warm up valve has been removed,I have put on the bellowed up pipes(no leaks) I put the Diesel site intercooler boots all around and am still getting full boost on my gauge and it has done this with 2 different turbos (I had an oil leak and got replacement and had my stock one on while waiting for garrett to decide to replace it) So what else could it be?

Have you checked ICP under load?

Low ICP will cause the fuel to be injected at a lower pressure and will not atomize correctly. This will give you an inefficient burn resulting in black smoke.

Borrow some type of scanner or make a mechanical gauge to check it. If it will not hold 2800-3000 psi more than likely your pump is weak, or you have an HPO leak.

No I haven't checked that lately I have a scanner I'll do it today. Thanks Mike

I checked and at WOT it was above 2700 psi at a 40% duty cycle. Mike
