[QUOTE="The Brad, post: 1216289, member: 14154"] Here's an update. I've learned that a cylinder contribution test doesn't work when the AIH is missing, it ends the test prematurely. So the next best thing is to cancel 1 injector at a time while watching MFD. Sure enough, when I canceled #7, there was no change in MFD. I reinstalled my AIH and ran a CCT and #7 failed. I emailed Tim @ PIS and he rushed me out another injector (I'm about 7 months past the warranty, thanks Tim). I moved #5 inj to 7 and put the new inj in cylinder #5 just to be sure there wasn't something else going on. I put about a hundred miles on it and so far, so good. The truck doesn't shake anymore and it's more responsive. I still have a fuel knock on the drivers side that sounds hollow, like someone's hitting the valve cover with a screwdriver handle, but it goes away on deceleration.There's also a loud tick and using a stethoscope, it sounds like the tick is coming from #2. I guess another session with a breakout box is in order. Once I got some miles on it, I put in a Swamps HFHV IDM and it feels a tad smoother and I notice my inj pw got shorter by about 0.1-0.3ms at idle and cruising. I've only driven 10 miles with it so far. I haven't towed yet to see how egt's are, but I don't see any difference while daily driving. [/QUOTE]
