FCD on N/A pressure sensor?

I have a broken turbo map sensor and a good N/A map sensor.

Here's the deal, I need a Racing Beat FCD due to less back pressure. I was told if i purchase an FCD that I won't need to purchase the turbo map sensor that i was planning on getting and that the FCD will work with an N/A map sensor on a turbo car.

Normaly using the n/a map sensor on a turbo car will cause you not to be able to enter boost and bog down instead i know this, but the fcd counter acts this sort of N/A map behavior?

are there any cons of doing this set up? run rich/funny or anything?

Turbo sensor on a non turbo does not work right and neither does a non turbo sensor on a turbo car work right.

One is a two bar sensor and the other is a one bar sensor.

At atmospheric pressure their output voltage to the ECU is dramatically different when you compare one to the other.

So don't waste your time and effort putting a FCD on a non turbo boost sensor. That's all.
