The pump pressure adjustment screw is not linear so I cannot verify the exact turns. I suggest flow testing the system for one minute is very accurate.

You can use the MAF as a secondary input for trigger or compensation. IDC is not reflective to engine load than a single dimension signal just as boost. MAF is good but it cannot be compared to the IDC as it it a composite signal from multiple sensors and engineering hours.

Use IDC for trigger.
