Hello all, my name is Mike from California. I have a 2003 gmc 5.3L and I am looking to get a programmer or tuner or something along those lines. Any recommendations will be greatly appreciated and pros and cons. Thanks a lot.

- Oil Consumption

  Ok well I guess Lake disagrees with me on a few points. I call oil consumption pretty basic. Rudimentary. He calls it "really complicated." I think 1qt consumed in 3k miles is a lot. He says that's normal. In 22 minutes, he'll use his natural talent to explain oil consumption to anyone watching this video. He covers everything from obvious engine damage to how normally functioning healthy engines consume oil by design. Lake explicitly states how you drive will impact oil consumption. Shut up and watch:

  Check for broken bolts holding the exhaust manifolds to the heads, common problem. Dorman makes a repair piece if you find you have broken 1s and don't want to do the surgery to replace them

  My dealer says it's the 6.6 from the HD modified for the 1500's. So, my money's on the 6.7.

  Took some leg work, but I guess they want to keep my business.
