If you're talking about TIE Interceptors for the game "X-Wing", you can see an image of the stat card over on Boardgamegeek:

Primary Weapon: 3
Agility Value: 3
Hull Value: 3
Shields: 0
Actions: Focus, Barrel Roll, Boost, Evade
With a Pilot skill of "1", this gives you a card worth 18 points (I think). Want to fly with better pilots, increase the point value by "1" for each point you increase his skill.
Then, from the "Unboxing the Millennium Falcon SPOILED" video, we learn that Boost is:
Boost Action Reference Card
This card explains the rules for performing a Boost action. Ships with the (arrows) icon in their action bar may perform a boost action. To boost, follow these steps:
1. Choose the (Straight) 1, (Gentle Left) 1, or (Gentle Right) 1 maneuver template
2. Set the maneuver template between the ship's front guides
3. Move the ship to the opposite end of the template, and slide the rear guides of the ship onto the template
Performing a boost does not count as executing a maneuver. A ship cannot boost if this would cause its base to overlap with another ship's base or an obstacle token.
