I just recently swapped tire sizes now running a 35x12.50x20 and my speedo is off around 3-4mph at 70mph. I see rough country has a calibrator but my question is what happens when its flashed over my efi live auto cal? Duramax truck. I dont think I can just send my tuner in anymore and have it updated since the crackdown.

  Our local Ace Hardware made a chip key for my 2015 Silverado for$100.00; that's a lot less than the dealer. I suggest you give them a call and have your VIN,title, and/or registration with you.

  Trying to install a jump seat instead of center console, but have to remove the Bose sub. Any ideas on where to relocate that sub or replacement options for under seat with harness? Haven’t messed much with audio before.

  ...was looking to see what the 3 post OP had to say since they've got a personal issue here and 3 different threads they made within the same time period...just today....and then regurgitating that some owners on facebook and other forums have issues which is a small number out of total ownership of 3.0 Duramaxes.

  Just a guess based on the mentions I've seen on this forum... Failing coolant control valves (LM2, LZ0) No start / long crank issues (LM2) Thrust bearing failures (LZ0) Timing chain failures (LM2) Fingers crossed GM has more revisions and updates in the work because the 3.0 is awesome (when it can be trusted).
