I can't believe how different the bcs behaves on they dyno vs the street. I'm glad you switched back to the MBC though; I was getting sick of hearing you whine about the thing
I like the powerband on your car; its sooo phat! Its a wee bit of a shame your top end isn't better, but I think its obvious that the limit of the stock turbo on pump gas has been reached. This powerband shall serve you well for a long long time! This is a nice safe, conservative tune.
