i basically did one of the things that was recomended to me to try and it has changed something.. it feels nicer to drive and definatley feels quicker . the boost gauge in 3rd gear used to go to 24 then as the revs increased the boost slowly went up a tiny bit wher as all i did was the exhaust and now straight to 30 and stays their. it will be going to the garage some time to be checked but i didnt want to take it before only to be told to change the exhaust or exhaust cam..
