When I turn it over it's barely running and missing so bad I was afraid it would cause a mechanical failure so I didn't even let it run long enough to look at the afr. I was always told I could just upload a stock itr map and add 30-50% fuel to compensate for e85 across the board and it would be close enough for a base map but I'm just trying to get a lil more info or maybe luck into a map from someone on here that will get her running safely

The method is a good way to start. You have to make sure the injector data is correct and you have to calibrate your TPS properly. The s300 portion of the forum is not as active but i am happy to help.

I went through the tune and got everything running good. Idles about 950-100 steady, afr at idle is about 13 though so I could probably toss some fuel in that area and wide open throttle it's staying right around 12.0.

Yes, increase fuel at idle until it reads 14.7. At wot I usually aim for 12.5.
