If Someone had a custom tune, then added a cut out, is it necessary to retune. How much of a difference (in tuning) would the cut out make if it was open or closed? I'm guessing none??

I try and do all of my tuning with it open. I noticed with it open I tended to pick up some kr at specific rpms. By tuning with it open I can be certain that I've eliminated all kr. FWIW, I see the cutout (especially with LTs) as a sound mod and not necessarily a hp mod.
