Guest sl1d3r Posted June 5, 2013 Share Posted June 5, 2013 No the wastegate spring mod is used on the mkiv to because of the pressure caused by the turbos the wastgate can be forced to open early and then boost is not held threw the rev range which is the trouble i am having :/ thanks anyways for replying Link to comment Share on other sites More sharing options...

Best to put the car into TTC mode to see if that fixes it and then you should know what your issue is straight away. Have a look around about 2nd turbo not coming online and you will see that it is a very common issue. Well worth doing before messing about with the waste gate spring!!!
