I have a quick question before I have a shop work on calibrating and cleaning my Weber DCOE 40s.

Is it normal to have the Crossflow engine hesitate and spit when throttling up from idle? Mine is fine when idling and when above 3000 RPM, but in between I get a lot of popping, spitting and hesitating. Some of it is undoubtedly caused by the aggressive cam, but my hope is that the carbs can be set up so it is smoother on the road and in traffic.
