Its a pain. you have to load the engine tune and then when it says done you may on plug it ,don't just reboot. then go through it again and the second time around you can pick the trans. it annoys the hell out of me but that's the only way I can get to it. have you seen the trans thread started by (I believe) blackpepper ? it works pretty good,for not being CMR.

FWIW I have always noticed better mpg's with higher octane, especially when running in hills, tune or not. But I also dont try to drive for mileage very often.

^ yeah we have some hills, but most of them are on the west end of the state. and don't get me started about the wind, my truck (work) has been leaning over like it's trying to make a " v-8" commercial for way too long!
