Very true... didn't think about the gearing and tire size issue, was just thinking along the lines of trying to figure out how many mpg I'll drop after i raise the hp some. And you could be very right... i might bump up to 350-400hp and still drive "nice" and get 24 mpg hwy.
By drive nice.. I'm talking shifting @ 2-3 grand, easy acceleration and interstate speeds of 70-80mph.
Edit: for the record.. interstate speed limit is 70mph here and 80 is still only 10 over. Just wanted to make that clear before I caught the "wrath of god" from some....
