I'll let the experts explain exactly what was changed , but believe it was something to do with where o2 sensor mounts hitting steering column.

Stu from BMR can elaborate on my wild guess
Definitely good bang for buck with the downpipes.

Yes the front o2 sensor is repositioned to give more clearance on our RHD steering racks.

I'm guessing it would be easier to do the ECU mod JB4/Cobb etc CAI & DP's all at once but it would be nice to add each part 1st to feel the gains each mod makes on the car in terms of power and the acoustics.
No need for a re-tune afterwards

Doing it all at once doesn't make a difference compared to doing it in stages... best to do it in stages in fact so you can indeed feel the differences being made.
Most N54 tunes only take 30mins to install, whether a piggyback or flash.
