I have 18,000 km on my truck, or just about 11,000 miles. Three times it has done something which I can only describe as a wastegate popping. It happened at about 8000 km, again at 9500 km, and then most recently at about 16000 km. Each time it has been while cruising at a steady speed. Once with a sled deck and two sleds in the back (about 1500 pounds total), the other two times while hooked up to my 16k lb fiver. With the sleds, it just made noise, sort of like a wastegate popping off a few times? But when hooked up to the trailer, I really noticed that it didn't have any power while it was sputtering. It was bucking noticably. The third time it lasted for about 1 minute. After it quit sputtering, it was fine. No CEL, and I just got back from the dealer, nothing on the starscan. Any thoughts? I am taking it in on Thursday and they are going to have a tech look at it. I don't really want to throw an XRT or Smarty on there before they get this figured out.
