So I had a bully dog tuner for my truck and haven't had it plugged in since I got a new engine installed a few years back. Found it today and found someone who would buy it. Contacted bully dog and found out that I would have to change my tuning to "stock" to be able to unlock the device so the guy could buy it from me. I told them that my truck was already stock and they said that I just needed to run the stock tune to be able to unlock it. So I did that and it cut my engine power and turned off ABS and Stabilitrak. Cant go over 25mph, truck shakes, sounds weird. I have no idea what to do and their customer service is closed for the night. I have work in the morning, any suggestions?

- Question about torque specs and possible reason for noise

  alldata.com will have the torque specs for all those bolts.
- loose lug nuts
  
  By davester · Posted 4 hours ago
  
  maybe make sure both the hub and the rim surfaces are flat and corrosion free? I know for both my '04 and '12 3500, which are both duallies, I've had the rear wheel lugs loosen sometimes, after tightening, then driving a bit and then re-torquing them. The fronts also sometimes, but much less common vs the rears. And if you have the flanged flat face (vs the acorn style) lug nuts, make sure the flange part can spin easily. I spray some fluid film on the outside and work it into the groove until the flange can spin easily, making sure not to get FF on the threads. This seems to have helped with the lugs getting properly torqued, so they stay tight.

  So I’m looking to swap my 2022 halogen to 2024 led 2500 hd front. I have the grill the headlights - halogen to led 8 to 12 pin wiring harness. I just found the front bumper upper cover facia and I’m looking to see if anyone has a parts list to help me out with. I’m going to need the mounting brackets to install the grill and headlights. I’ve been on some gm parts sites and it’s just horrible trying to figure it out.

  Another massive smartphone in the dash! I guess one wasn't enough. Just what I want. 🙄 At this stage GM would have to pay ME to drive anything they've built the past 20 model years. Once was enough for me. Learned my lesson.
