Popping and banging
I have a MY00 witha full decat, downpipe and backbox. Recently when I lift off (or reverse) it has started to pop and bang a bit.
I am about 3k away from an interim service, is this something to do with the air/fuel mixture or something else? My knocklink is not showing any activity. Any help would be appreciated. |

Edit: I have the std dump valve still in place |
Thanks, standard dump valve but running 1.2 bar 248.1bhp.
You've put my mind at rest. |
