I stumbled on this on another forum. I picked one up for my Ecoboost so that I could use it for a boost gauge. It's really an all in one type tool. It could be used for 1/4 times, HP, Torque, rev limit alarm and trouble shooting codes. Fully customizable and has several pages of gauges. Well worth the price. Requires OBD 2.
