My truck a 2002 hd 2500 5 speed, threw the following codes today P PCU 1693, then P ECU 1689.Truck has been running great for 140000+ miles, I replaced the lift pump awhile back with flowmax from bd. It ran fine after the replacement no codes, and fixed the problem of the engine surging, when I first engage the clutch, had to fuel the engine up a little, even in first, but more present in 2nd. So i was thinking the stock lift pump was weak.I just added a Bully Dog Outlook with PE to the truck. After this I noticed the surging came back (when on a power level other than stock) especially when the engine cold, have to fuel engine up a little when engaging the clutch, or surges as I call it. When in stock mode, everything is ok.I realize this is not a forum for Bull dog support, being this is my first power enhancement gizmo, My questions are this:1) Is this normal after a power enhancment gizmo is installed ? I notice when the code(s) where thrown the bully dog power cycled, and yes the power connections are sold from what i can tell2) If the bully dog is messed up end of story, if not then any suggestions on diagnosing a P1689 code ?Thanks in advance,Tony
