Jerking or rev hopping when letting off throttle

Hi all, when I have my rev hang (overrun) option turned off I get a jerking in the car or a rev hop and I can feel the car jerking as well as being able to visibly see the rpm needle go up and down about 50-100 rpm whenever I let off the throttle . The higher in the rev range the harder the car jerks or hops. I had read in some forums that I need to increase the amount of fuel in the low load ranges or lengthen the injector duration but just wanted to get some input from some of you guys. Thanks!

Other overrun tables might need to be adjusted. Post the calibration you are running and a datalog. I can take a look at it.
