[QUOTE="RedVenom48, post: 16259492, member: 166576"] Totally normal for high lift/duration cams. The idea behind the factory camshafts is to give good performance off idle up to near factory redline while remaining emissions compliant. Performance camshafts alter when and how the intake air flows into the combustion chamber. An old saying of "Getting it up on the cam" still applies. Cams typically need higher engine RPM to work. You probably have crazy airflow from 2000-7000 RPM now, most especially when in boost. :D Unless its a Daily Driver, Id leave them in and enjoy the performance benefits for what they are. Or.. you know... I could pull my factory cams out and we could swap... :D :D :D [/QUOTE]
