I have a 05 CC F350 dually with the auto trans...I installed a Juice box, 5" exhaust, and AFE air box at 200 miles. This past weekend I was pulling my other truck to a show 300 miles north and 1/4 of a mile from my house I blew the intake tube off of it, making a nice dent in the hood; and I had it down on stock. I put it back on and it made it another 130 miles before it blew again, this time at the intercooler below the air box. I noticed right before it blew that she was pulling really hard and showed 32 psi of boost on my guage. I dropped the trailer and bobtailed 35 miles back to the nearest dealer. They replaced the hose assembly with the updated aluminum one. I went about my business, but noticed that even in cruise it would pulse every so often and the tranny seemed to be slipping. I took it up the road about an hour ago and turned the box all the way up to see what it would do, and its not even half of what it used to do, and that was only 9000 miles ago. I pulled the juice box off of it just now and am pondering taking it to the dealer tomorrow. I am just wondering if anyone else has had this scenerio and what remedied the problem. I would think it different had I just put the upgrades on it, but since they were installed so early, I doubt that is the problem. And to make things worse, this is the first load I hauled. I am kicking myself right now for selling my 7.3
