Ok so I did the Pikey R600 mod, and didnt really notice any difference as mentioned above. Very happy with the job i did nice and neat. Took about 2 hrs as i wanted a stock look. Just waiting now on the blanking piece. Need to look at wifes Kodiaq as it looks like it has the same intake but the intake looks like it maybe on the right hand side? Just need to lift the cover piece when she gets home.
On another note i fitted the BMS pedal tuner. Now that mad a difference. Just switching from stock to the first setting you could feel the responsiveness straight away. Got it on first setting (green) plus 2. Car feels like it should from factory. Did an obd11 scan no faults.
