Help stuck in Montana
1997 2500 5 speed 4X4 Afc live 3/8 rubber lines from tank to injection pump and return Tork tek overflow Egt , boost, fuel press gauge Boost elbow at 31 Stock timing I believe Traveling from Florida to Idaho with about 11000 on the trailer . All was well for the first 2200 miles. Started to get real high EGT's and was falling on its face from 3 to 4 and 4 to 5. A little from 2 to 3 . Started smoking badly after shifting and took forever for turbo to catch up. By the time it does EGT,S are already going over 1200. Boost is still climbing so I believe the turbo is good. I checked shaft play and all good. I'm thinking maybe an injector went out. Fuel pressure is good at about 30 At the begging of the trip I was on a pretty good grade (long and 5%) I shifted into 4 and was able to maintain 55ish at 1000egt and about 24 boost no problem. No it would be into 1500 before I got close to that. Any help appr...
