Note carefully that de-cat is now illegal in the UK and an instant UK MOT failure

Any tampering with the emissions control systems is an immediate MOT failure

My XC90 has an existing Cold Air Intake: the intake air is sucked in at the very front of the vehicle, well ahead of any hot engine components.

Re-mapping is another story: mine is remapped and works well.

I was observing 1.4 bar of boost and intake air flow of over 400 kmph today
