how is ecutek different to verso.. there both programs that hack into the OEM computer, thus utilizing what points the standard ecu has to offer.

I dont understand how u can say one is better than the other in terms of functionality. Or that its been proven in motorsport. Of course the OEM ecu works fine under any condition, thats why it was put into cars in the first place.

It all comes down to the tuner, to extract the most out of the ecu.
