I've seen mixed stories with DPs, but nothing on fmic.
I doubt that a dealership or warranty company could prove a FMIC caused a problem, except in concert with a tune or piggyback.

A DP, however, by definition interferes with the pollution-control equipment and turbo circulation. Depending upon the problem, they could well refuse coverage.
