I had my boost / fuelling adjusted last week and Ive noticed that I get a lot more popping and banging on overrun now than I did before. What could have caused this?, I believe the fuelling has been increased to match increased boost would this have an effect on overrun?.

I also "think" im hearing a slight bit of "pinking" too and the tuner has turned the dizzy slightly clockwise when viewed from the cap end. Does this need knocking back a tiny bit? (I cant think it would be det as I believe its running richer now)

Cheers,

Stu
