Nooooo! The resistor trick does not work as advertised... I tried that on my 300E and promptly lost 10% in fuel economy over two tanks, it went back to normal when I re-installed the resistor. There was ZERO power gain. Pulling the resistor doesn't max out the advance, it puts the system into sort of a limp mode, but there's no real power loss either. Results seem to vary from car to car though, but I definitely don't recommend this particular mod. BTW - I was running premium at that time. With the resistor back in place I can run 89 octane with no adverse affects... no power loss, no knock, no loss in MPG. I don't recommend that either, as individual cars may react differently...
