Interesting. The thing I was wondering about was rear gears..they say 3.08 standard with the 6 speed and that would be ok as the first gear in the 6 speed is a stump puller, but I am hoping they will still let you order 3.42's or even 3.73's....that would be crazy out of the hole. Ordering guides are not up yet last time I checked....

Welcome to the Obamanation of the vehicle market, mileage above all else. (Although with the 6 speed might have more gears to downshift to, won't know until test drive....)

bigger injectors

Injectors don't make more power. The tune must be adjusted to make better use of E85. It was just interesting to me since they never advetised a different e85 power rating before
