Any ideas?

Have a 07.5 6.7 cummins DRW with DPF delete, egr/cooler delete, and smarty jr. Ran it for 300 miles or so with no problems. Mom took it to a horse show today and she said it ran funny. Took it out and normally not really any smoke output. Stepped her down at 55 and it just rolls coal. Not what i want. Hit the exhaust brake and it kinda does a powerstroke whistle/squeal and then goes to the normal exhaust brake. Wondering if its the turbo or some leaky gaskets. Haven't really had any time to do investigating. Any ideas??

Most likely the vanes in your turbo are stuck. Take it for a drive and run the crap out of it. This should loosen the soot up and free the vanes. Another tip is always drive with the exhaust brake on, it keeps those vanes clean and moving. Hope this helps. You could also go to cumminsforum.com and do a search.
