Yeh I was reading that I just thot wasent looking for huge power would have got away with it on the upside think I may have found my problem the car has an external wastgate with an apparent 7psi spring so I set the wastgate so there was hardly any pressure on it also when I got the Manafold and wastgate there was no gasket so I got some exhaust gasket of ebay and cut it to size but it's realy thick like 2 or 2.5mm so Iv just taken the wastgate off to find that it's set about 2mm below the body of the valve it's self so pretty much it would never be making a seal and I can push it in 2 or 3 mm with a very light push with one finger
