On early 7.3L Power Strokes, the PCM will only read a maximum of 23 psi, which won't satisfy us as we're already maxing out our 35 psi gauge on the street and plan to run even more boost in the future. The sensor came with a connector/pigtail, requires a 5v and a ground connection, and has a male 1/8-inch NPT fitting. In just a few short hours, we'll be able to accurately read vitals like ICP, duty cycle, injection timing, injector pulse width, boost, and many other parameters, as well as perform our own buzz and cylinder contribution tests!
