Specifically, because of a few minor bolt-on mods? i.e. intake, exhaust, etc. (not a supercharger or anything big)

I know that one answer might be, "No, they can't refuse warranty service if the mod didn't do any damage."

Nonetheless, we know that some dealers can be pricks about tuning - has anyone ever had a dealer look under their hood take a look at their GruppeM, Conforti, etc. and say, "Nope, we're not going to touch this."
