I had the unfortunate experience of loosing my turbo last month. Caught in the middle of nowhere NEw Mexico it cost me a fine tune of $2150 by the time I was done, plus $165 to be towed 30 miles... (I'm more ****** at the tow then the repair). At any rate, getting the truck back I notice not a woosh as everyone describes but more like a grind, almost like a bad bearing sound when I decellerate quickly. It does worry me as I pull all the time and stress that turbo I'm sure. Second concern, Cummins replaced with a stock unit , I am running a TST box, when I pull it goes 3 and 3 and no more. i try to watch the guages and do the best to keep everything down. I'm not sure if I trust this truck anymore, granted I got abot 60,000 miles on my old turbo and TST box. Total miles on truck is 130,000 now. I'm scared to death that I'm going to spin another turbo before to long. I am wondering if it might be better to trade this thing in for on of the new kwickspool ones you guys are now talking about. I don't know alot about these things but I can tell you one thing, I don't like a Ford showing me up and I push the limits at times to make sure I smoke him. I'm not a kid anymore but still a bit of a sucker I guess. Any advise?
