hi can anyone help me on a smal problem i have with me series 2 rs turbo,ive had the head off to replace the gasket built it all back up but the turbo's not boosting, car runs sweet ticks over fine but when i run it down the road the boost gauge is only going up to the zero ive disconnected the actuator and the wastegate seems to move ok as does the turbo impeller,has anyone come across this before. its probably something silly but its driving me mad
