Reason being after tune with power commander with stock filter at idle seems choking and running to rich
If it's been "tuned" it should not be rich or lean.
I agree a filter sometimes is a good addition to a build but in some cases the stock filter actually produces the best HP. I'm not sure if a filter adds power in your case. It seems that not a lot have tried it.
