I would get that stock dp asap its really not worth it being flagged at the dealer and even if your tech is cool he'll give you shit about the dp. This is the only reason why I have not gone fully-catless yet my tech does not care about tune but tells me if im catless no warranty work will be excepted...

Return your car to stock and go from there.. try to find a cool service tech that will be ok with mods.
