I'm not worried about that. I will definitely not be using Dinan as their tunes are always on the conservative side and thats just not me.
BurgerTuning is good, I used to have a 335i and I've met him personally a few times when he installed it on my 335i and then at a drag strip. If he comes out with an X6 piggyback then I'm definitely game for his product.
I'm waiting for the X6 M to be available and will be getting that modded. 650-700HP would be nice.
