Hey, i have an AUI falcon with an auto gearbox!

What i want to know is;
1. Is there any point in having one?
2. Is there better performance from having one?
3. Should i get a single or dual stage shiftkit?
4. Legallity of a shiftkit.

Any info would be good as i am currently looking to enhance my drivetrain before i break out the pretty ponies!!! lol

Are we talking electrical or mechanical?

i have an electronic one, 2 stage from shiftkits.com i think.....
was good at the start, but know i think the ecu has learnt it .... i might try reset
shifts nice and hard...
