Stopped by and installed on my stock '12 F350 over the weekend. Just happened to be starting an 800 mile roundtrip up to NH and back. So far couldnt be happier. The guys at IDP were standup, proffesional, and came off as having a whole lot of technical expertise and knowledge about our Fords. I'm very wary about anything aftermarket on my truck. They took the time to really explain how it works and what it will actually do. Seemed perfect for someone who doesnt tune.
Over the last 800 miles I gained between 1-2 miles per gallon, and feels a bit punchier..gives me that lower, 3.73, 4.10 gear responsivness feel on the throttle. No issues to note. Im a pretty tame driver, but shifting, etc doesnt feel any different than stock. Time will tell, but so far Im very impressed.
