JMS BoostMAX Performance Boosters

Plug-and-Play Power for EcoBoost-Equipped Fords

BoostMAX's wiring harness simply plugs in under the hood to instantly unlock the hidden power within your EcoBoost engine. This is done by increasing throttle response and adding boost to optimize power output without the need for OBD-II programming. BoostMAX can be combined with most SCT Handheld Programmers, utilizing a JMS custom tune file for your vehicle to completely maximize engine performance in only minutes!
