    None of my mods are really mods... Just a couple of visual changes.

    I thought deleting the resonator caused a check engine code to pop on. Anyone know of that for sure?

    DoD is where the oil goes. It's a known issue with the GXP with the displacement on demand crap. When the engine uses only 4 cylinder, the other 4 are still getting oil. All 8 run burns the oil in the cylinders. Only way to get around it is have it tuned and have DoD disabled. Some say they never noticed a difference in MPG, some have seen 3-4 MPG.

    And smile it's Blacktooth Grin!

    taking off the res will not put an engine light on.
    what WILL put an engine light on is deleting the cat/o2 sensor

    if you unplug it you get a code, so like said above looks like it needs to be tuned out
