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
Did you get a re-tune done after installing the DP's?
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.
