Update - they came out with 2 new tunes: Tow and Economy. They also added a lot more options - you can custom tune the transmission shift points, and firmness. There is also something called torque management which I don't know what it does. I loaded the tow tune in tonight and will be towing 6000# trailer about 2500 miles over the next week or so. Empty test drive had a goosey throttle again but not quite as bad - gas milage seemed down but I did not drive it far. I'm not sure what pyro temps should be, but it peaked at 884 deg F on Pyro 1. I'll update in a week or so on how it does. I did not mess with the transmission - I love how it shifts stock.
