The aFe BrakeLogic exhaust brake controller for 2017–2019 Ford diesel trucks with the 6.7L V8 is a plug-and-play module that electronically closes turbo vanes and commands transmission downshifts to create engine braking. When engaged via the factory Tow/Haul switch, it can produce significant retarding force—up to 130 retarding horsepower and as much as 70 psi exhaust back pressure—helping control speed on descents and reduce brake overheating when towing.
