Pressure Advance < 0

[ditomaso]

Tried the lines method of pressure advance and 0 was the best option but could still be a bit better. I'm unfamiliar with this setting -- is there a way to dial it back so I'm starting from a setting less than 0?

Negative PA is very unlikely.
I'd suggest you try the PA tower method, as the results of line method may be flawed if the initial layer quality is bad.
