This!

There has been a lot of progress made in the US on weight reduction by changing;
- brakes (maybe not so much with the smaller units fitted to the 1.5 but better performance?)
- Wheels (ND specific 17" 6ULs)
- battery (replace factory lump with Lithium)
- exhaust (performance gains here too).
Interestingly there have been no (real) improvements (actual measured that is) by changes to the intake so far......
Most other gains are from ECU tunes but these are primarily for the 2.0L version, all are variations on reflash techniques.
Probably get in touch with OVtunes as they are most prolific and will likely have a 1.5L version tune plus also offer remote fine-tuning for your vehicle.
