Lots of questions, such as what does the unit "/psi mean and why is the range of the graph 0.1 - 5869, with the readout being near the top most of the run? I do not think this is an apples to apples comparison here.
End of the day, a MAP sensor reads absolute pressure (hence the A and P of MAP), and if you had a car at sea level with the ignition on but engine off, you should get a reading of 14.7 psi from the MAP. Turbo can add to that, and vacuum will subtract from it. So, an engine under vacuum during, say engine braking, would see a MAP readout of something less than 14.7 psi.

I blew out my back so I'm in the hospital recovering from 2 fusions and 2 laminectomies. I did find a place that would finish my exhaust, so I think I'll have them remove the dynomax muffler and just do a dual out the back and move the diverter valve to before the cat with a nascar style oval dump behind the front tire. Should add sound and yeehah. Being old and broken sucks hard, but hey, life could be worse. At least I have Jesus in my heart and I'm looking forward to the rapture very soon.

Thank you, prayers are always appreciated. If you want to hear about the rapture, listen to Pastor JD Farag's Bible prophecy sermon from 3/24/2024 on jdfarag.net. He doesn't give day or time, he only talks about the Hebrew holy days.
