Cheers for all the help.
For stage 1, boost should be set to 1 bar, which is for the sake of argument, 14.5psi. Much above that, and the standard 2 bar MAP sensor simply 'lies' to the ECU about manifold pressure, ie tells it there's less air in there than there actually is.

With the amal valve connected (provided it works!), the ECU will control the boost as best it can, and according to the boost values written to the chip by the author. As long as you've got the actuator set in just about the right position, the ECU can take over from there. To lower boost, lengthen the rod by half a turn for each 0.02 bar (0.3psi) less. To increase boost, shorten the rod by half a turn for each 0.3psi extra.

Having it setup is a great idea - as for setting the fuel pressure yourself, you'll need (obviously) an accurate fuel pressure gauge, and the recommended fuel pressure setting from the chaps that wrote the chip. As Tabetha said above, normally this is 3 bar with the vacuum pipe connected to the pressure regulator, but sometimes it's set slightly higher.
