2015 eco with 180, 000 mi. I bought this truck used and did a full delete and programed with R&B Calibrations . fast forward 1 1/2 yrs, truck throws a 299 code and goes into limp mode so I take it to the same person that did my delete. He installed a new turbo and when he was done the truck would not stay running, it would start and shut right off. after many attempts to fix the problem I programed the stock programed and limped away 2000.00 poorer on to the next Garage.
