Had a friend who bought his Ecoboost there. I bought mine at another dealer but they quickly became my dealer for everything as they are so helpful and probably one of the largest set of dealerships on the east coast, if not the US.
I know they aren't a Ford Performance dealer(I dont think) but I've had great great service at Koons Falls Church. Could careless the aftermarket work I had done and always willing to find out an answer even to off the wall questions.
I passed this along to my contact at My dealership. They are really mod friendly so the tech is actually going to experiment on his EB and see what he can find out. I'll update soon hopefully.
Can't say enough about Adam and how he handles his tunes. I've had custom tunes in the past and they are nothing like him. He isn't even afraid to point out when I do something I shouldn't. (3rd gear pull from 1500 rpm....) Out of 10 I would give him a 15!!
I installed the Speed Factory IC a few days ago. Loving it. Seeing about 5-10° above ambient temps. I had a longer pull and the temps actually dropped lower than ambient, not sure how that was possible, but interesting.
