Anyone have any advice, or know of any reviews of Superchips vs. APR ECU upgrade for an Allroad 2.7T (03 model)?

Superchips is cheaper and offer less power/torque, but APR (as well as more power) offers ability to change between various ECU programs via cruise-control stalk (and allows a few other things like ability to reset fault codes etc).

I'm interested in info on smoothness, reliability, fuel consumption, noticeable differences between them in terms of power/torque etc.

Any info or pointers appreciated!

Thanks
John
