Obviously Motec offers a better resolution and a few other real cool functions compared to other ECUs.

It really comes down to how much you really want to spend on your car, a Possum Link ECU, Autronic, ECUTEK , Microtech all could make power it comes down to the tuner and how well he can tweak your map.

I personally have a Link ECU, it makes power and its ok on the street bar a few surges every now and again. (Which could be fixed by dumping in more fuel into the map im told)

Hope i've added some fuel to the fire.
