I have a 2006 cummins. I am running the smarty jr on sw3 and recently installed a bullydog watchdog so I could keep an eye on egt's. The boost display on the watchdog is saying I am only getting 25 lbs of boost, but it will read 25 at just past half throttle and if open it up I can hear the turbo spool up and the truck runs great. I am wondering if other guages like the ones from edge that gather readings from the OBD port are usually accurate of if I have another problem. I am having a hard time believing I am only building 25 lbs but this is the first diesel I have had in some years. I am kind of upset to spend 250 bucks on the display and get the wrong readings, but I am not sure if it is the watchdog or the truck?
