Hi there, this is my first post but I actually sell bully dog through the company I'm with.
Now there are a few steps to take in making sure the driving coach is working properly, going through the vehicle setup wizard and checking the vehicle speed and economy read outs for accuracy.
I know the wizard comes up automatically, but go through it again to make sure the information is correct. you can never be to sure.
Did you pick a realistic goal, if it's set to high you will get a bad grade because it's harder to reach. I would start mine at 16-19 mpg since EVIC tells me I'm getting an average 14-15 mpg because I'm not light on the throttle. You may have a different goal in mind.
Lower the Sensitivity setting for the acceleration/deceleration bar and work your way up over time. Everything should be started from the bottom and worked up.
Just pretend it's a video game, you have to reach the next level and the difficulty is set higher.
Not sure if any of this has helped and I can't remember if the GT comes with Watchdog instructions but here is the link to the Watchdog.

Remember, the longer you drive the more accurate it gets. The coach can't learn the students habits in 2-3 days. wait 3 weeks to a month and if you still have issues call their tech line. 940-783-9915 or 866-285-5936 from M-F 8am to 5pm MST
