Switching to 2 Bar MAP
I wanted to know how to change from the stock one bar to a two bar MAP sensor in HP tuners. If it helps, I have a P04 ECM. Do I have to get a file, or a whole ECM from a supercharged monte, and transfer my existing tuning changes to it in order to be able to use a 2 bar MAP?

only info I can find on it with a screenshot, but I can't look as my laptop is down to find it. |

You aren't missing anything. The only way you can go about adding the 2-bar MAP is by installing a supercharged OS onto your car.
MAF tuning and a wideband for 1-bar if you don't want to do the OS switch. |

That's what I suspected. I only plan on running 5-8 psi of boost, would I be able to run that with just the stock MAF and a wideband?

Don't think you can since a 1 bar will only measure 14.5 psi at wot. Which is atmospheric pressure. Once you build boost it will be 14.5+4 or 5 psi which means map will be maxed.
