hi all, i have a boost problem. recently had a new turbo unit on my series 2. it was working fine. all of a sudden it stopped boosting. itl boost very little in 3rd and 4th cos of the biigger gears but 1st and 2nd see no boost at all. i have checked all hoses, i have also bipassedthe amal valve by jus having the hose straight from turbo side to actuator and stil nothing. its as if the actuator isnt opening. also have fitted a new actuator. any thoughts??
cheers all
