Ford 6.0L Power Stroke Diesel :: 2004 - Turbo Won't Have Boost?
Jun 17, 2015
I have a 2004 Excursion with the 6.0. Lately it seems like the motor just doesn't have the boost it should. Funny thing is that the boost reading through the edge cts seems to be right. Under full acceleration it will pull 27 psi boost and 3900+ ICP pressure. No codes are being thrown. It just doesn't "feel" right (seat of the pants) and it also sounds louder but I don't known this for sure.
Where does the CTS get its boost reading from? The truck has new boots on the hot side from riffraff. Anything I can check?

Having this problem, what to do to correct it? There is no hole in the boot and this just started about a year ago. Does not do it all the time.

Just wondering, what the max boost rating on a stock turbo, stock engine in a 2011 is. I know the gauge goes up to 40 PSI, but I don't think I've ever seen my go past 20.

Check engine light is on says low turbo boost but gauge says it has a lot of boost. Only happened after I put catalytic back on for smog test. Before that no problem.

I have a 2013 F350. Since it was new in August the turbo has made a chattering sound that sounds to me like the waste gate (if it had one) is opening and closing rapidly. Almost like its building boost and dumping it over and over again. Usually happens when it is in 6th gear around 1700 rpm under light load. It also does it from time to time while plowing snow. You can power through it or let off and it will go away. My local dealer where it was bought new put a new turbo on it and the problem still persists. The truck just turned over 8k miles and has been in several times in attempt to resolve the issue. They say that there are no codes on the truck nor does Ford have anything on their service web. My dealer claims that no one has ever had the issue.

I've been having issue with my truck lacking boost over the past month or so. The psi levels are normal in the morning when I start it up cold, the problem almost always occurs at start-up when the truck is somewhat warm and has been sitting for an hour or more after use. I've had boost levels at idle from -0.14psi to -0.56psi and as low as -1.2psi when driving as the problem is occurring, but it eventually kicks on and goes to normal levels after several minutes of driving. After originally taking the truck to a local diesel mechanic I was told it had EGR codes and they recommended installing an SCT tuner and cleaning the EGR valve to solve the problem. I had them install an SCT 5015 tuner and clean the valve but I've still been having the problems with boost.

I have an '03 powerstroke 6.0, 4 inch turbo back exhaust. truck had lost boost and would cut in and out if i got on pedal and now a little bit of oil is collecting at tip, could this be because of bad turbo seals? And could the turbo still be alright? Another thing, I'm losing coolant, and I have noticed when I took the EGR out and cleaned it, the valve itself was the powdery black carbon, the cooler was wet, and I know it's not supposed to be like that. I am not thinking head gaskets yet, cause if it had a blown head gasket, I wouldn't be able to drive it. It is currently sitting, and I'm just trying to fix it. Would I be able to fix the turbo seals myself?

I'm relatively new to the 6.7 engine , I have a 2014 F-350 SRW with aprox 51,000 miles on it. Normal driving I see about 8 to 10 psi of boost even under moderate acceleration although at times it will go to about 18 psi at WOT and it does this with heavy loads. At moderate acceleration the boost will jump to 10 psi quickly but immediately stop there and sometimes as the RPM"s increase boost pressure decreases. Only issues I have had with the truck was a clogged EGR cooler.

This is a common problem. Mine goes to dealer in the morning for it. I haven't seen any recent posts within the last year on this. Did ford ever find a fix for my problem? When going up hill at low rpms I lose boost and hear the stutter out the intake..

The ford dealer in Las Vegas replaced my turbo with a remanufactured one. Coming off the line (like quickly pulling into traffic) it goes flat on power until I get a few RPM's. Even with the old turbo it never did that and I drove it for the last 30k miles with it throwing the low turbo boost code. They put a little over 100 miles on it for road testing (I did have other things that they worked on. {4x4 2006 F250, 6.0 engine, 110k miles and I bought it new}....

Well I am at a loss now. Rebuilt the turbo with a new wheel and kit from Riffraff. I still have no power, no boost and no codes. The new wheel whistles. I can hear it. It sounds way better than the old one. But still no power. I really don't know what to do now.

Ok so I just replaced the oil cooler, added 2 coolant filters, changed the oil/filter, and both fuel filters, and installed the updated turbo drain tube. I get it all back together, it takes a minute before it will fire but I figured that was normal for not having any oil in the sump under the cooler and changing both fuel filters. Everything seems fine, checking for leaks and I notice that I don't hear the whistle of the turbo so I go look at my edge CT and have zero boost and it stays at zero even if I rev it a bit. Obviously I didn't redline it or run it for very long maybe a total of 10 minutes over several times.
I will note that I did find a plug for the driver side injectors wasn't plugged in the first time I started it, but I shut it down pretty quick and plugged it in. So then after I noticed the turbo not spooling I used the chip to pull the codes and had a whole bunch related to the unplugged harness and one for turbo underboost. Figured it was because the harness was unplugged so I just cleared the codes and tried again, now I'm not getting any codes but I'm also not getting any turbo boost the only code that it is throwing is the P1000 "on-board diagnostic systems readiness test not complete" do I need to go drive it for the learning sequence because I had the batteries disconnected for a couple days?

The 2004 and 2005 turbo is interchangeable and can you replace the bearing in it.

I have an '04 6.0 and it doesn something strange. When for example I am going up a decent grade hill and passing, if I have to let off the throttle and then re apply, the turbo won't build boost, it sits at a couple pounds for a few seconds. Then after a few seconds it will build boost quickly again and work generally as normal. If it doesn't respond and I really need to get it to build boost NOW, if I push the accelerator to the floor, the delay shortens and it will often kick down a gear and then build boost. So if I gently accelerate, very slow to recover, if I hammer it, much quicker but regardless, when it's happening it's almost always the same situation, fully warmed up truck, warm/cold/freezing day and it happens when I back off and re apply. Thinking maybe a worn unison ring but not sure..

I have done some searching on this, seen a video on YouTube but haven't read anything that is firm on what it is. We pulled our 5er for the first time last weekend and the chatter was pretty pronounced in the Arbuckles here in OK. I was running around 65 mph when I hit the largest hill and as I was climbing my speed naturally dropped, boost was around 17 - 18 psi when the chatter started.
Is it something to be really concerned about? Is there anything to be done to prevent it? I'm pretty much still stock, only deletes have been airbox to 6637, and I deleted the heater by turbo for the boost gauge. Other than that everything on truck is still stock.

It started after a blue spring upgrade. my turbo would not spool until we revved the engine hard then it kicked in and it's kinda worked since then.. it feels like the truck is struggling on acceleration and the boost builds fast up to 30lbs, the EBP seems to be stuck at 21.48psi until your in 3rd then it jumps and I have power again, also the turbo dumps (farts) if I let off even a little until the EBP jumps then no issues. I replaced the sensor and it's stuck at 21.48 all the time.
Now, I unplug it and it jumps between 26 and 28psi, plug in the old sensor while it's out laying on the motor (not installed) and right back to 21.48. I don't know where to go with this and it's my only truck so I need it running. also it was blowing the intercooler boot off at the turbo during a normal acceleration and the turbo spool has a howl to it when EBP is stuck...

I've got a 2002 Excursion which has been giving me a little trouble lately. I've got a DP tuner, 4" exhaust, afe stage 2, and gauges (boost, trans temp, EGT). I've been running these for about a year now without any truck problems until recently
So I noticed over the past couple weeks it has gradually been taking longer for the engine to start. Started off by just having to turn the engine over a few more times. Now it has turned into having to turning over the engine for a few seconds, then turning it to off, then trying again. It always starts on the second attempt to start my truck and sometimes really hard where it blows out a little black smoke.
Not sure if this is a correlation to the problem above or not, but I've also been losing boost pressure, and I'm not sure when this started since I haven't been on the highway for a while. I noticed this because this weekend I drove on the highway and saw that I was blowing some black smoke every time I accelerated which has never been the case.
So I check my boost gauge and see that I'm sitting at like 3-5psi when I used to be at around 10psi+. I also noticed when I accelerated the boost pressure would increase like normal but then quickly drop once I stopped accelerating which is unlike anything I've seen before in my truck. I don't seem to notice a huge difference power or throttle response, but then again 95% of the time I'm driving under 40 mph to get to work. So this problem could have started the same time as the starting problem, but I can't say definitively.
What this problem could be, what to check or test?

ive noticed my boost has been going down lately. At first I thought it was a boost leak so I replaced all the intercooler boots and both sides of the intercooler pipes. That diddnt change anything at all. I recently got new injectors (200/30%) and a hydra tune for them and it was quick the first few days i was running with that setup, my boost has been dropping and currently at WOT I can't even get to 10lbs of boost and it is noticeable driving, it's slower than it was stock. There was no play in the shaft of my turbo and the turbo in there is only 2 years old. Could the turbo be bad already? Or is there anything else I can check before buying a new one. I have an upgraded hpop and the 6637 intake.

My friend is working on a 2004 6.0 F-250 and it has used 75% of the coolant in the overflow bottle in 5 days. Can't smell coolant either. The inside of the tailpipe is wet soot black and there are wet spots on the tube coming from the intercooler to the turbo at the turbo and the intercooler. He's thinking EGR cooler.

Weird thing happened today. Was out running errands, and upon pulling out into traffic I felt the truck lag a little. I figured it was the typical trans hiccup we all experience from time to time. As I continue driving, I notice I don't have any turbo boost.
I'm cruising around 55-60 and when I slowly give it gas......No boost. I stomp it and the turbo gauge slowly climbs to about 12 psi. At this point I waiting for the truck to throw a warning message and none came.
As I'm reaching my destination, the speed limit is 30 so I'm just putting along and any acceleration I did, the boost needle wouldn't move. I arrive at the store, and when I got back in 5 minutes later and drove off, My boost was back. Truck operated normal for the 25 minute trip home. I thought a similar thread was started but I couldn't find it.

My truck is all stock and I am running in performance tune? And my friend the former owner said I need to let her loose about 75 percent of the time I am driving it because it's my DD and I do not tow anything on a regular basis. I do not want to stretch my bolts by unnecessary pushing, I don't know if I'm even pushing it hard but I normally get the turbo up to about 30 psi is that to much?
