thanks for the info guys , i tried the car with out the pill and only got 0.5 bar of boost . after a long look on here it seem a better option to get another pill and drill it out . i will try 1.2 mm first and see if that helps if not then trying 1.5 mm . looks like a trip to the local subaru breakers , which helps as i can get a price on some rear calipers and kill to birds with one stone lol .... kev
