No christmas tree on the dash... The MAP sensor isn't completely non-functioning. It is reading incorrectly, so the incorrect values and scaling could cause the super-rich condition I'm experiencing. I'm waiting patiently for the UPS man to bring the MAP that Gary from Sprintex USA overnighted to me. I should know tonight if this is the magic bullet.
We looked at the BARO reading with the key on and engine off, which gave them an idea of the baseline. It wasn't what they expected, so that's the test.
I'm working with Mike Litsch from Diablosport and Gary Turner from Sprintex USA. Both guys seem to be giving my problem honest effort. They've both looked at the variables and both agree that the MAP seems to be the culprit. I'm just frustrated, but these things happen.
I appreciate you starting this post and giving a favorable report. It's hopeful for my situation. I'm looking forward to your video when you get a chance to post it. I'll live vicariously through you. :)

I received the new MAP a little bit ago, and it didn't change anything. I hope Gary and Mike can figure something out tomorrow, because I'm sure they won't mess with it over the weekend.
that video is great. That SC whine is very cool to hear.
Stay positive rgeorge, that scream is in your truck too. Just have to get it sorted out. Once fixed you wont remember any of the current misery.
rgeorge, May I offer an alternative explanation on the "bar" of a MAP sensor? BAR is a metric measure of atmospheric pressure. Simply put, absolute seal level is 1 BAR. As you move up and down in elevation relative to seal level atmospheric pressure changes. It's important to know the pressure in the manifold without regard to outside atmospheric pressure so MAP sensors read "absolute" pressure (not important here). A 1 BAR sensor can read accurately up to 1 BAR or about 14.5 psi at sea level. A 2 BAR sensor can read up to 29 psi and so on. The Bosch code you posted is for a part originally equipped in a Fiat 1.5L trubo. It is quite likely a 2 or 3 bar MAP sensor because it has to read boosted pressure values. All of that said:
If you have an electrical multimeter you can perform some basic tests. There are three pins on the MAP sensor wire harness connector. They are +5 volts, ground, sensor output. Turn the key on to run (don't start the engine). If you set your meter to DC volts you can pin the black meter lead to the ground and you should find one of the other pins with 5v on it. If you can't make a circuit or the voltage is more/less than 5v the the issue is in the harness (look for damaged wiring or bad connector, etc.). If you get 5v then you're good to go. Testing the MAP sensors themselves is a bit harder - you need a vacuum pump. But a simple test is to put 5v and ground to the MAP sensor and read the output. The output should be close to or exactly 5v because there's no vacuum applied to the sensor. If you bench test a MAP sensor and get way less than 5v without vacuum applied, then the sensor is bad. I write all of this because I went through all of this.
I strongly suspect your wiring harness is OK and your MAP sensors (now you have two) are OK. What's not OK is what is happening in the computer when manifold pressure changes and the voltage on the output side of the MAP sensor changes. Now you're in calibration land and the tune file tables need to correctly address what to do with the MAP voltage supplied to the computer.
You might ask one of the other USA sprintex guys to email you their file and send it Mikel at DiabloSport and ask him to compare them side-by side just to make sure they aren't missing something.
