So i've been going through this aggravating thing for months now and its becoming quite unbearable. Ever since i disconnected my battery to change my spark plugs with NGK Iridium 6510 plugs on my 2010 Ms3, it bucks and jerks rather violently when i hit bumps and uneven pavement. It also does it...

The car feels like it will start to cut out or well hesitate when I give it full throttle. My fuel pressure is great, and my boost consistently hits its target of 22lbs. It will start to hesitate at full throttle sometimes, my best description would be I floor the car and it just starts popping...
