I agree with Scheides...

If you are not 100% use to the settings on the AVC-R, unhook it and get a MBC.

The duty cycles on the AVC-R arent the easiest to get down and most likely are your problem. If you really want to use the EBC, set your duty to 100% and your boost to where you want it. Do a pull but be ready to let off because you will overshoot your "set boost". This would be only to test if the duty is too low.

What is the "duty" at right now?

You could also try raising the percentage 5-10%, doing a pull, raising, doing a pull... Until you get to the boost you want to be at. Continue raising it until you over shoot the set boost by 2-4psi and dial it back a few percent on the duty.
