I installed the Max Boost on my 2018 F 150 Limited and it has lived up to the claims. Before I installed it, the truck had a 16 second quarter mile time. Once I installed the devise, it ran the quarter mile in 13.7 seconds. I'm purchasing a 2019 and the first thing I will be doing to it is install a Max Boost!! The 2019 Limited is using the Raptor motor, so the controller for this motor is different, but I'm happy to pay another $309..
