Tunetechnic in Auckland did an awesome job. I sent them a spare ECU and they tuned it to our set up, the exhaust and air intake etc. They estimate an extra 15kw and 25Nm.
It goes well, the torque is there all the time and peak power gives a real kick at the top end. The auto box is in its element, its smoother and more predictable. It has transformed the car. I also reckon it's the best looking VR6 in NZ!
