6.0 surge problems
Hello, everyone, I have a 06, 6.0 auto w/ airaid air filter, bullydog triple dog downloader (which is now removed from the truck).
Heres the problem.
while accelerating or even at constant speed there seems to be a surge or pulse to the engine you can feel it and here it in the whine of the turbo, if you watch the tach as it climbs up it will fall alittle then climb then fall so on and so on,in any gear, it's way more noticable going up hill,and even worse pulling a load 7-8000 lbs. while pulling the other day the egr or blowoff valve popped 3 or 4 times and the hole truck jerked, I slowed down,maintained speed and it hasnt done it again.I thought if might be running lean so I changed the fuel filters, the primary was nasty, the secondary looked good.the problems is still there but it is a little better. oh I have 16,000 miles on it. The problem was worse with the downloader,so I removed it as to trouble shoot the problem.Its not the transmission, it smooth and firm.
Thanks for you thoughts, I go the the dealer next monday, I would like to know what Im talking about when I get there.

Warning, Warning, Danger Will Robinson...!
The only advise I can offer is to put your truck back to a 100% stock configuration--even the intake--BEFORE you take it in to the dealer... If you have turbo surge issues, they'll burn you for the AM intake (perhaps) but they'll surely black-list you for the tuner. Do you know have to do the KAM reset, & VGT relearn strategy stuff? Read this thread
You can also try this, but get more input first... I'm just an enthusiast, not a tech.
KAM (keep-alive-memory) reset & VGT learn procedure <o> </o>

- Drive the truck to bring it completely up to operating temp - VGT learn procedure requires that the oil and coolant temps be high enough to allow EGR operation...
- Disconnect both battery ground cables at the same time... turn the headlights on for about 10 minutes - this will deplete any devices that even have a chance of retaining KAM in the PCM. <o> </o>
- Turn off the headlight switch and reconnect the batteries. <o> </o>
- Cycle the key to the run position twice to allow the clear procedure to complete..... Pause in the on position long enough for the wait to start lamp to prove out and pause in the off position for 10 seconds to be sure the PCM has "gone to sleep". <o> </o>
- Start the truck and leave it idle for at least 5 minutes... you will likely hear the turbo pitch change several times during this period as the PCM learns the necessary duty cycles for accurate VGT control..... <o> </o>
- Now you can road test it and the process should be done...

6.0 Surge
thanks for the reflash advise, but you didnt say wherether this is a normal surge, or a problem ie a broken surge. If its broken what is broke, egr or turbo or may just a reprogram? I dont want to go into the dealer and they tell me its normal if it isnt. Its been doing this for awhile (2 months) started very slightly, then gotten worse.Im just curieouse.

Call me jaded, but I've experienced too many incidence in my days, over many, many trucks. The diagnostic finding of "normal" to a condition that shutters the owners confidence in a vehicle, and impedes the vehicle's performance is not easy for me to accept... Normal MUST come with details as to why it's normal, not just that it's normal.

On a side note the surging was almost gone when I got the truck back and now is slowly getting worse again.

I recently posted the same problem. I called my friend (service manager at the dealership) explained the problem and he told me to drive it hard for a couple of days. Odds are the vanes are sticking. My truck surged at a steady speed around 30 -35 mph. He said if that didn't clear it up bring it in and they'll take the turbo off and clean it. My truck only has 16000 miles on it and i don't drive it much. He also noted to not let it idle any longer than absoutely necessary. 6.0's hate to idle and it sometimes causes this problem.
Hope this helps...just my personal experience.

About two months ago, my truck began doing almost the same exact thing. Only did it when I was towing and holding the RPMs steady while on an incline. It did it to me two weekends in a row, so I took it into the dealer. The dealer ended up testing the EGR and turbo and ended up replacing both. Since I got the truck back, It hasn't done it a single time. Dealer seemed to be right on with their diagnosis and they didn't give me any flack with ANY of my mods, including the programmer.

My dealer would have nailed me to the wall in a heart-beat.

Thanks for the replys, I going to the dealer today at lunch to drop off my 06,Im a gas guy, race trucks ,mud trucks, street trucks, this is my first diesel and turbo, hell its the first new car I have ever bought.I just needed to be sure I wasn't crazy, Im not the type to go to the dealer everytime a bulb blows out.I know alot of people like that and thats why Dealers are (sometimes) hard asses. I understand it, as do most of you.
I will let you know what they say was the problem.
Thanks again
Lee

Could be a sticking VGT actuator.
Have them check this TSB 05-21-05/Broadcast Msg 4459:
2004-2006 engines that exhibit a light surge on light acceleration up to 50 MPH, typically after a cold start, at steady speeds between 1800-2800, or when climbing a grade (towing or not), may have a sticking Variable Geometry Turbo actuator. If diagnosis leads to replacement of the VGT actuator, the turbo lube oil line--P/N 3C3Z-9T516-BA; should be replace as well.
Hope this helps
