Installed a JMS BoostMax and PedalMax to my Expedition. For a quick rundown of what they do check out the link on their homepage http://www.jmschip.com/boostmax-performance-for-ford-ecoboost/ What a difference!! Totally made the truck even more pleasing to drive than before. Extra power for passing and the throttle response is much improved. For those of you that have a drive by wire system the PedalMax really made the truck feel like it has a throttle cable again. And the Boostmax works as advertised. It really puts you back in your seat now when you give it some of the go pedal. The fact its warranty friendly is a plus and install time between the 2 was less than 30 min. Very happy with the decision to do this over a tune.
