If your car is an auto I would stay away from EOC as your engine needs to run for tranny fluid to flow. Unless you have Saturn or certain models, you risk damaging your tranny durng EOC.
Read your cars manual. If it states that you should limit how far and/or fast you can tow your car with all four wheels down (Engine off drapping/pulling) then I would stay clear of EOC. EOC is of many benefits availble to those with manual tranny
EDIT: OOPS, my bad. Its a Saturn. Forget this post, at least for your car, ZVolen

Okay, I think I'm done thinking out loud now...

Ah, that's a fosho thing, that yer throttle position in the car will not match up with what the throttle's actually doing since you have drive-by-wire. Anything above like 10% pedal will give you ~30% throttle, you may go WOT at 60-80% throttle. It's just nuts.

Ya, Thanks for looking out but as you notice I have a Saturn, which can be towed in nuetral so EOC shouldn't hurt it *crosses fingers*

I would hate to push the vehicle for better numbers only to find out it lead to its death.. Kind of ironic.
