Default Irregular boosting

Hey guys,

I'm having problems with my Dahlback chip again, as I did at first. The boost is very inconsistent. Somedays I have it, some days my car feel bone stock. WTF???

Any ideas?

Default Well that doesn't mean it cant stick.

I have been in BeeJohns car and I don't think he has ever had the issue your having on your car. The only things I think that will cause the inconsistent boost would have to do with your bpv, wastegate or N75 sticking open at times.
