Experiences with new Dinan x35i tune for E70?

[X5 4.6is]

I have the Dinan tune on my 2012 35i SAV (July 2011 Delivery). For me the power delivery is impressive! What I noticed first is how the quickly the revs climb and hold the gears before shifting as compared to stock. Notably quicker yes, but that's probably due to the extra programmed torque output. Fuel econony, very very subjective, but averaging 15 - 18 mpg in the city and over 20+ on highway trips. Like everyone else when the benzo is topped off the needle seems to move quickly south...Bottom line for me this bad boy is a whole lot more exciting to drive. I have no problem running with my brother's 2013 50i M Sport/Performance...
