So I've got the extruder feed issue figured out but I'm still trying to dial in the inital feed length the loading process. I do have stringy tips after a tool change, which part of the tip shaping block of code do I tweak, and which way do I tweak it and by how much?

Well, stringing is about the temperature and how close the reloading of the filament gets to the nozzle.
Make sure you are not retracting the filament before the tool change too far... As our code should be going back to 1mm before the nozzle.
