Hey bud look at turbo and then find the actuator and follow the vaccum pipe and you should find a small device which the pipe goes in one side and out the other. It should have an knob which you can use to adjust the boost the car will run. You should have to unlock it with a small Allen key. If this device is there turn all the way down. If it's not there check the pipe hasn't come off at the other end. If all is good you prob have an actuator issue (the bit what allows the car to build pressure) Jamie
