I don't think that there is any difference, the EDC pump mealy has an electronic control whereas the mechanical is just that, mechanical. What weight are you towing? When did you last have your engine tuned ? My 300Tdi also doesn't like towing, it's hardly a speed merchant when its not towing but a slug when it is, but it's only a 2.5 litre and a heavy weight but it's very economical.

As far as i know, the only difference is one injector on the edc has a sensor within it and therefore has a wire to it, it does work just the same as the standard injectors though so there is no trouble if it's disconnected.

The EDC was added mostly to autos because the auto box sapped the power, this could be why you think it is sluggish. You could try tweaking the injector pump to get a little more power, a lot of people go overboard and end up with lots of smoke but there is potential for a useful increase in power without ruining the fuel consumption or making MOT emissions tests difficult.
