Probing Routine Causing Issues In Program

So this issue isn't necessarily related to Fusion 360, but more of a code issue I'm having. I have a part I'm making in a Haas VF-4 (NGC) with a 4th Axis (A) rotary. I cant post the part/file but I think my question can be answered without it.

 

My programming and post come from Fusion. Using NGC post w/ A-Axis reversed. Part is a cylinder with domed top, stood straight up. Starts with A @ 0deg and all of the work I'm doing is at A90. or A-90. with a lot of back and forth between the two. 

 

Now my issue, I'm using a hand written probing routine at the start to probe both center and top of my part, I am using G254 in the program. Running my program as is, with probing, my whole part is shifted off center in Y axis by .02", If I skip past the probing and start at my first tool and let it eat from there, I get a good part. So, what am I missing with the probing that's causing an issue? 

 

Here is the probing routine and start of the first cutting tool.

Sorry for the long post, any ideas on what's going on would be greatly appreciated!
