the real point here is that downpipes and warranty tend not to play nice. Ive had CPO work done on my car and nothing was ever said about the FMIC, i t
removed cobb and the dci before taking it in. Downpipes and a bov will be tough, unless the dealer is extremely mod-friendly. regardless, remove AP completely, if they find stage2 mapping your warranty claims could be denied.
