Good writeup Phimosis. I'm glad they finally got yours up and running. I'd be happy to have mine back at this point with the same numbers you are getting. However, i too am not happy with the fact the cars are not attaining the advertised numbers. In some ways i feel duped.
So far, i've received 3 different tunes since last Thursday and still no resolution. And with the long weekend, i have to wait til Tuesday for the work to continue. At least you had the benefit of having your car sitting in their garage and talking with them face to face. They won't even reply to my email...how's that for customer service?
Anyways, good to hear about your car.
