tons of mods that should be mandatory (IMO) since you asked. here's what ive done so far in my first six months of ownership:

- Eurocharged ECU Tune - +30 bhp and 27ft lb torque
- Spring Booster
- Spacers for stock wheels 20mm front and 18mm rear (makes the stance perfect!)
- Lowering springs (H&R)
- Charcoal Filter Delete
- RPI Air Intake System - 17hp gain (at speed i think)
- RPI 13% Underdrive Pulley - 12 hp gain (on certain dynos)

check out some of the other forums, you will get much more information than whats compiled here tho...

Enjoy that beast!
