    Can anyone help me out, I have a 2013 Coronado glider kit with a 1999 dd4 12.7 liter engine that came from Detroit as a 500 hp reman engine. I had this thing tuned by Pittsburgh power an set at 600 hp a few years ago. I just had it reprogrammed to a 550 hp. I'm running a 171702 bw non waist gated turbo & just switched to a bw k31 turbo. I can not get over 30 pounds of boost, I've tried & tried for years, I'm told I should be putting out 34 to 40 lbs of boost, on a hill or a pull it falls flat on its face. I'm running a 13 speed with 3:55 rear ends. Can anyone help ?

    Stop getting ripped off by Schittsbirgh Plower and take it to Antrim Diesel. They'll straighten it out for you.
