Well, I don't know if it because of the EGR being disabled by the GDE tune or what, but I just changed the oil about 500 miles ago, and it is still fairly clean. Previous the the GDE tune, the oil would be pitch black after a trip around the block after an oil change. I've had the ORM & elephant hose mod since almost day one, and the oil has always been pitch black.
So why is it cleaner now? Either the ORM wasn't really disabling the EGR, or the GDE tune is making the engine burn much cleaner. What do you all think?
