I brought my Tbird in for the initial 500 mile service. I was having problems starting it until I did the 12 minute drill to reset the ECU. Now it starts ok but I did ask the dealer about doing a Tors download (eventhough I have the stock pipes). They recommended not to do it. They asked if I was putting regular octane gas in the bike and I said that I was actually putting in premium. They said that with the most recent ECU downloads that I should use regular octane. I said what about the middle octane and they said no, don't even use that, use regular. Anybody doing that?
