Livernois Motorsports MyCalibrator Touch Tuner

A handheld touchscreen gadget you plug into the diagnostic port under the dash to load a new engine calibration -- it changes fueling, timing, shift points and throttle response for more power and better towing behavior.

why this one — Part number LPP631151, built specifically for the 2018-2020 5.0L F-150 (this generation added direct injection on top of port injection) -- matches this catalog's Gen 3 boundary exactly. 50-state CARB-legal (EO D-752-7), with Livernois's own site claiming peak-vs-peak gains of over 25 whp/35 wtq (up to 44 whp/72 wtq at points in the curve) on 93 octane.
