Ranger Sport 4.0L 2wd 5spd man. I installed the jet Chip as the second part of an update to improve street driven performance, torque/power 1500-3000 rpm. This update along with a K&N 57-2561 have improved torque/power in the 1000 > 3000 rpm range for daily driving, light hauling and trailer towing. Acceleration through the gears has also improved. Gas mileage city/hwy 24 mpg, hwy only not yet checked.

Really a nice device. I am amazed at all you can monitor with it. My main reason for purchase was to monitor the transmission temps when towing my 17 ft travel trailer. But I'm also monitoring fuel mileage and throttle position. I only gave 4 stars because the included velcro for mounting allows for too much vibration. Replaced it with a 3M Command strip refill.

Super easy install. The device is tiny but still really easy to read. Tons of information.
