I'm going to be getting a Eurocharged Tune done on Saturday along with a group from Southern Ontario. I use a ScanGuage II with XGuage capability and I was wondering if any members here have recommendations for programming particular useful reporting aspects from the car. What parameters to monitor Before and After the tune?

I've added Horsepower to the set of readouts but there are a whole host of attributes that have the potential to be displayed/monitored that I have no clue about.

Can anyone shed light on this topic or share programming details based on their experience with this device?
