I tuned mine myself with HP tuners. Since I already had a laptop and HP tuners for my Vettes, I went ahead and bought another license for the Hoe. I increased the % for V-4mode (think I'm at 40% throttle IIRC), got rid of the speed limiter (had my Hoe to 140mph according to my gps navigation), 93 octane, and a few other things. I saw 4-5mpg increase with the tune I did

4-5 MPG sounds like a heck of an improvement. Is this mixed city and highway driving?
