ok I played with my jerk and acceleration settings more and got not much of a visible difference, if anything. I downloaded and Installed the new firmware and am noticing a lot less difference at higher speeds than slower now just to fine tune it. Any advice ??

I'd suggest a systematic approach. Prepare a sliced gcode file to test with. A tower of some kind with sides long enough to get up to your chosen speed. I like to use 100mm/s so that it's easy to scale the speed with percentage. Use 2 or 3 walls and no infill. Make sure your slicer doesn't try to control acceleration settings. Set jerk to something easy like 600mm/min (10mm/s) Then use the m204 gcode command to modify the acceleration for print moves increasing every 10 layers or so. You could even add it to the gcode file itself so you don't have to do it manually. Then print it a few times at different speed factors and you should be able to identify a sweet spot. You could also measure the distance between ringing ridges and use the formula from that thread to find your ringing frequency.
