Lately car seems to be not pulling as well as before. The boost is still holding at a steady level (around 0.9 bar ) but is just taking longer to reach it. Also seem to be using up water in coolant system but cant see any obvious leaks and oil isnt creamy. The car itself has a stage one chip, exhaust, air filter and the actuater is not standard but i am unsure of the exact specs as i never fitted it, all i could tell you is that it is blue!!

Would be greatfull for any sugestions thanks!
