And to pre-empt the next question... on an RS2 ... you should see 3.8bar +/- manifold pressure on the fuel rail
so at 0.5bar vacuum on idle you get 3.3bar on the fuel pressure gauge
and at 1.5bar boost you should see 5.3bar on the fuel rail... this is pretty tricky to prove of course unless looking under the bonnet at a dyno for example... unless you have an emulator and a hand pump to fool the ECU into letting you idle with silly high fuel pressure.Paul Nugent
