Ok changed my clutch cable and pedal the other day and ever since i've been loosing loads of boost. Used to peak at about 1 bar and hold 0.8 but now it peaks at 0.8 and hold 0.6! I know a boost leak could do this, but what about a dirty air filter? i decided to rinse mine out with warm water then as i'm impatient in din't let it dry completly before oiling it and putting it back on Oh the car is also a bit harder to start as well.
