No power and black smoke.

Ok powerstrokers I need some help. First of all my truck is a late 1999 F350 90,000. I bought it to pull my 24ft Jayco camper (4500lb) trailer. I recently compared it to my fathers 01, that is stock other than a KN filter and exhaust, and his almost twice the truck as mine. Heres my mods.
1. ATS turbo housing for turbo surge issues.
2. Cleaned EPS and tube from manifold.
3. S and B intake.
4. New batteries.
5. Intercooler boots checked and no obvious leaks found.

Symptoms.
1. Lack of power when pulling.
2. Black smoke, even with smaller flatbed trailer, during acceleration.
3. Smoke when accelerating when truck is cold. (unknown color)
4. Louder when engine is colder than warmer.
5. Cranks twice as long after wait light goes off than fathers PS. (relay has been checked.)

Mods for the next yr.
1. DP tuner
2. exhaust
3. bigger tranny cooler

Truck is scheduled to go in for a CCT this week and I am going to have GPs checked also. Any ideas? Thanks in advance. I am new to diesels so bare with me. John

Do you have a way to monitor boost?

The main thing you need to do is get it hooked up to a scanner/monitor to see what is going on. You should watch things such as ICP, IPR duty cycle, MAP, etc...

It is normal for these trucks to be a little louder when they are cold compared to when they are at operating temp.

Make sure to watch ICP when cranking. The PCM needs to see 500psi before it will fire. This could be the issue for your longer cranking time.

I do not have any way to monitor the boost yet. As money comes in, and I can afford it, I will be installing gauges. This week its going in for a buzz test, cct, and a scanner test. Are these buzz tests accurate? Also, when i read the voltage on the other side of the relay, it only was 9 volts. After I seen the voltage made it across I assumed the relay was OK, but shouldn't the voltage be near 12 volts like the battery side? Thanks for the reply. I really want this to be a good truck, but i know it has more to offer than this. John

The buzz test is accurate when the truck is bone cold(hasn't ran for the day yet). Once the truck is up to temp it almost always passes the buzz test.

9 volts is very low. You are right on your assumption that it should be higher.

Ok then how about the CCT. does the engine need to be up to temp or cold? Plugs checked today and they only had .8 ohms. All checked ok. Pulled intercooler boots off and cleaned them and checked for any leaks. All ok. GRRR.
