holley 4160 bogs at cruise

I have a similar set up with a similar hesitation. Went to the 35 shooter & reset idle under load & it seemed to help but didn't cure. I run 16* initial & 34* total by 2500 RPM. I'm thinking pump cam, may be not enough fuel early in the pump shot for the the cam (xe268 ). will be trying the red or orange cam I'll post if does indeed help.
