Under Extrusion Help

I need help with my K1. After a blob failure that destroyed the original hot end, I upgraded to a unicorn nozzle. Since, I have not been able to have consistent prints. Whereas before, just about everything was perfect.

I have done numerous tests, but none of them have really helped. I have gotten closer after I rooted the printer and began using Fluidd via Orca. Using the bed mesh I was able to level my bed better, and have seen better results, but I am still getting under extrusion. I have also replaced the nozzle that came with the unicorn set just in case it could have been faulty nozzle. Still nothing, I even installed an upgraded extruder, and nothing there either.

Edit:
For clarity, this is what I get when doing a flow rate test.
