People do, but they shouldn't. At best, the S-AFC is ok for fine tuning. It is not good for large adjustments with out ECU. When you screw with the sensor inputs to our ECU, you get some unexpected results (like ignition advance). This can be very dangerous on a turbo conversion. As mentioned, you will need a stand-alone, high gain fuel pressure regulator like a S-FMU. 550's are a little big for a fuel system like this. Your engine will never run very well when set up like this.

A Missing Link is just a fuel cut defender. It permits the MAP sensor from seeing over a certain voltage (4.7) causing the car to jerk like a cheap whore.

Megasquirt is a standalone ECU and an SFMU is a rising rate fuel pressure regulator.
