Guigsy Posted March 25, 2012 Share Posted March 25, 2012 You need different spark plugs too really. 0.5 is first turbo boost pressure. Does the 2nd turbo cut in? Check the vsv's. Sometimes they stick and the 2nd turbo doesn't come on. Quote Link to comment Share on other sites More sharing options...
Slicknick Posted March 25, 2012 Share Posted March 25, 2012 Don't forget about upgrading the fuel pump too! Quote Link to comment Share on other sites More sharing options...
