For a DD, the Corvette is... irresponsibly overpowered. Reducing its power won't change anything but its 0-60 time- and like I always say IRL, I don't drive 60, and I don't live a quarter mile from work.

Hypermilers tend to corner hard, but they don't tend to drive cars that were built to do that. There's one corner in the next town that my daughter claims I take on two wheels. My son, who sits on the side that allegedly lifts off the ground, backs me up when I deny it. If I took them through that just once in a Corvette I'd never get any backtalk about my Honda.

I'm not up on Corvette aftermarket stuff, but since you're DIY wrenching, I'd look into taller gearing. Then aero- lose any downforce and block the grille, and then work on tires.

A high mpg Corvette is exciting, whether or not you hit 50.
