No I do not on my 2013.. It's still in the breakin period (200 miles)...but i do plan on getting one when that is all done..
I had a Dinan tune on my 2009.. you had to fill in some check boxes with approximately what you think you had in mods.. of course the mods list wasn't exactly the same as the check list and I think as a result I really felt very little to no change.
