There has been a good bit of talk of it over on Trat. Seems there will not be a "TOR" tune for the latest models. Something about the stock exhaust may not be AS restrictive as before so the base tune is a little richer. Add to that some are using the tune for the higher ethanol content fuel. Something about the tune expecting less "gasoline"(in the mix) and being slightly richer. Not sure I believe it but it has been suggested.

Brought it to the dealer and they said there is not a TOR map for it. The computer automatically adjusts for it?
Don't think our ECU will adjust for the changes across the map for the increased exhaust flow. The ECU "reset adaptation" process will adjust itself over time if not "forced" to via TuneECU. While that may help at idle and maybe the open loop/closed loop transition if things are somewhat out of whack, it is basically correcting for idle speed and not operating RPMs as I understand it.
