before you ask...

Don't worry about the "low" oil pressure. It's normal. Duramaxs' use a LPHV (low pressure high volume) system.

Don't worry about the "high" Coolant temp. The gauge sucks, and operating temps are about 185*, not 215* as the gauge says.

Don't worry about the voltage being low when you start the truck, it'll come up to normal after a few seconds.

Read all the stickies, and search, search, search!

Welcome, and have fun!

:D We try.

Oh yah, I forgot the biggest one of all. Read up On the main difference of the LMM Duramax, the DPF or Diesel Particulate Filter.

Read up on "Regeneration" too, it's part of the DPF Cycle of operation.

No no, it's not a concearn, it's just something to be aware of, by that I mean, how it functions, and what it's function is.

Nothing to be scared/worried about at all.

You're right, a lot of people do "delete" the DPF, it's easy to do. Just read up on as much as you can, and you'll get fetched up real quick. :D
