My buddy has a 2012 ford 6.7 and has done everything to his truck same as mine. Last weekend he spent all day putting a airdog 165 on his truck but after all was said and done it was doing worse. Emptying the fuel rail out and everything. So he done some research and found out his stock pump actually did better than the airdog. I have a 2012 LML and my truck is needing fuel bad so I thought about purchasing an airdog. But after his expierence im wondering if it is worth the $650 to find out if it will help my truck or not.
