You can find some information about 420A turbo fuel systems here:

I have never used the AFC Neo, but we have some information about the old S-AFC here:

I think you will have the best luck by making the large adjustments with the FMU and only small adjustments with the AFC Neo. The problem with the AFC Neo is that is makes changes to the manifold pressure sensor signal. This tells the original computer (ECU) to adjust ignition timing. Correct ignition timing is extremely important with a turbo engine. I recommend that you consider the Vortech S-FMU. It has many adjustments to control fuel pressure at low engine load (idle) and high engine load (turbo boost).
