[Yves082]

Hello, is there anyone who can answer my question I have a gmc canyon diesel 2.8l with an afe momentum programming airbox plus 20 hp with the urea system removed and I have a strange noise when I ride  with equal gas on the passenger side it looks like my air box like a sharp jerky aspirations is this normal?  and it's not in full acceleration and deceleration I would really like to know what it is and these are at risk thank you
